CHEMISTRY | IMPORTANT QUESTIONS | BSC | SEMESTER-2 | OSMANIA UNIVERSITY | @shivanipallela

[00:00:00]Students, welcome back to our channel.

[00:00:02]So, here in this video, we are going to discuss the chemistry gunshot important questions, ma, as many of you have requested in the recent times. So, here are the gunshot important questions. Whatever the questions I'm saying, no, just try to uh read try to prepare very well in the in that questions only your questions may expected in the examinations, okay? So, here this is your syllabus, ma. Just check out whether it is your syllabus or not. From second semester under Usmania University, first unit you are having inorganic chemistry. Second unit you are having organic chemistry, okay? Just check out the syllabus. Third unit you are having the physical chemistry and fourth unit you are having the general chemistry, okay? So, these are the four units you are having into your syllabus, okay? Only four units you'll have, ma.

[00:00:59]So, now first >> [clears throat] >> I'll give you the important questions unit wise long, okay? For long I'll give it first, okay? So, from unit number one, ma, as you're seeing on the screen, this is the first important questions you need to explain about the chemistry of d-block elements with the special reference. Means you need to explain d-block elements along to with all these elements, okay? Electronic configuration, variable oxidation states, everything you need to explain in this d-block elements, okay? This is the first important question. Second important question is about the chemistry of lanthanides. This is very important in top 10 questions also I have given. So, chemistry of lanthanides you need to explain in reference to this all, okay? So, just take a screenshot or make a note of this questions so that you'll get a clarity what you're reading from first unit. And third [snorts] and fourth questions, ma.

[00:01:57]Only four four questions I have given from each unit.

[00:02:00]Third question is about the chemistry of actinides and compare it with the lanthanides and actinides.

[00:02:08]And fourth question is about the magnetic properties and color of transition elements. So, most expected questions from unit number one is first question and second question, most expected I have said. High probability chances you're having from this particular unit is first and second questions as I have already shown.

[00:02:29]Clear?

[00:02:30]Now, second unit, second unit first important question is about the SN1 and SN2 reactions along with the mechanisms, energy profiles, diagrams, Walden inversion, okay? Racemization, okay?

[00:02:43]These are all with reference you need to explain SN1 and SN2, okay?

[00:02:48]And second question is about the preparation and chemical reactions of alcohols. You need to include in that Grignard reagent and Lucas reagent and oxidation reaction and Oppenauer oxidation. These are the four you need to include in this preparation of the reaction of alcohols, okay? Third question we are learning about the reactions of phenols, preparation and reaction of phenols in mechanism of this as you're seeing on the screen.

[00:03:19]Fourth unit is about the carbonyl components. So, here in this particular unit we can expect the most expected question is first question and this fourth question, carbonyl components.

[00:03:29]Most out of this four also top two is this first and fourth question, okay?

[00:03:34]Now, come back to the unit number three, my unit number three for long we are discussing as you're seeing on the screen this two questions is most most important explanation of the Kohlrausch's law and Nernst equation, Nernst Nernst equation. So, these two questions and third question and fourth question as you're seeing on the screen.

[00:03:53]Third question is about the types of electrodes.

[00:03:56]>> [gasps] >> You need to explain about that and fourth question is about the explain the depth edition of pH using. Here also most expected is first question and second question. Try to compulsory add that questions into your preparation.

[00:04:09]Compulsory we can expect that questions.

[00:04:11]Okay?

[00:04:12]Next one unit number four. In unit number four as you are seeing on the screen last unit.

[00:04:18]This is the first important question molecular orbital theory. Okay, in more diagram of thing you need to include in that H2 diagram into diagram O2 O2 minus O2 two minus. This is all diagrams you need to draw it. You need to construct a diagram. Second important question is about the molecular orbital diagrams of heteronuclear molecules. So as you're seeing on the screen, this is the third question mark as you're seeing on the screen.

[00:04:47]And this is the fourth question. Okay, most expected questions is first and third question. So all four questions long questions I have already finished.

[00:04:54]Now we'll go to the short questions.

[00:04:56]Okay?

[00:04:57]Short questions from unit number one as you're seeing on the screen. These are the five most important questions. So this five if you're learning means definitely it will be more than enough from unit number one.

[00:05:09]And coming back to the unit number two, these are the five important questions.

[00:05:12]Most important is Walden inversion and Cannizzaro reaction. These are the two most important extra important questions.

[00:05:20]And the unit number three mark as you're seeing on the screen transport number Ostwald's dilution law. Okay?

[00:05:26]Electrochemical series and conductometric titrations everything. Okay? And the last unit unit number four these are the five questions. Clear?

[00:05:38]So here also bond order and CIP rules are most important. That's it. These questions if you are perfect means definitely you will able to score full grade also. Clear? So, all the very best students. If you're having any further doubts, let me know. See you all in next video, students. Bye-bye, everyone.
