[00:19:15]electum.

[00:19:46]comment section.

[00:19:57][clears throat] Homog configuration.

[00:20:07]Yes.

[00:20:18]Less than equal to 14. More than 14.

[00:20:21]Less than 14.

[00:20:23]More than 14.

[00:20:46]Highest occupied molecular orbital.

[00:20:49]Lowest unoccupied molecular sigma star 2p.

[00:20:58]Very good.

[00:21:05]Lowest unoccupied molecular But obviously Pum XP 2 Sig TP Sigma TP Nitrogen nitrogen plus 2 plus nitrogen 2us.

[00:22:27][clears throat] Nitrogen 2us.

[00:22:33]Anyone? [clears throat] electigom [clears throat] nitrogen.

[00:23:05]Yes.

[00:23:11]Very good.

[00:23:14][clears throat] Option D. Yes.

[00:23:39]2.5 number of molecule count sorry elect [clears throat] in the given increasing order of the energy of the various molecular orbital is not true for Which of the following configuration.

[00:24:13]More than 14 molecular D. Oxygen.

[00:24:45]Very good. Very good.

[00:24:54]C Dig 2S.

[00:25:29]Elect Which of the following correspond to unstable molecule?

[00:25:55]Unstable molecule unstable molecule.

[00:26:14]Antibonding electondlest antib-bonding electronility more than number of antib-bonding electronic [clears throat] in the molecular orbital diagram. O2 plus ion, the highest occupied orbital.

[00:27:15]Highest occupied orbital.

[00:27:32]hypocr Still transition. for option ABC.

[00:29:08]Yes.

[00:29:11]molecular bonding and antib-bonding electity as comparison to antib-bonding electonding comp.

[00:30:06]The correct statement with H2 plus and H2 minus beta both H2 and H2 minus are equally stable. Both H2 plus and H2 minus do not exist. H2 is more stable than H2 plus.

[00:30:20]H2 plus is more stable than H2 minus 22 H2 H2 H2 H2 H2 number Countig H2.

[00:31:21]1 + 1 2 and unstable.

[00:31:56]H2 is more stable than H2 plus.

[00:32:37]H3 more stable than H2+. Losability stability comparatively less beta leable.

[00:33:11]electing bonding electron.

[00:33:45]So much concept.

[00:34:11]Yes. H2 plus more stable option ABC equally stable 0.5 Stability first comparability.

[00:34:51]Second bonding electond sorry antibonding electron comparatively less opt.

[00:35:32]H2us 8 plus H2 plus H2us said upon it.

[00:36:15]Bonding electron H2ability H2 minus more H2us.

[00:36:48]Yes. H2.

[00:37:01]Next.

[00:37:07][clears throat] Addition of hydrogen. Oxidation.

[00:37:17]Addition of oxygen oxygen Number n.

[00:38:15]Oh, oxidation number [laughter] zero, ozen zero, copper zero, F 0, P40, SI N sodium mercury amalgam state in case of metal hydridal hyd oxidiz minus one.

[00:39:37]HBRSUS.

[00:39:58]Next group elements, sodium, potassium, rubidium element, magnesium, calcium, oxidiz always.

[00:40:51]Group Group 13 Max 15 minimum group 17 + -1 One group 18 plus group 16.

[00:42:17]plus more Oxygen number one or minus Oxygen to N2.

[00:43:39]So [clears throat] except nitrogen question Your question more element Number element averageing.

[00:45:45]Xium + 2 oxusal x= basically average chlorine.

[00:46:10]is more than one total calcium.

[00:46:36]More important science group please.

[00:47:14]Chromium oxidization Butterfly. structure.

[00:47:57]Plus one plus correct answer structure. Yes, sorry.

[00:48:30]Oh, which of the following involving the transfer of five electron?

[00:48:44]Transfer of pipe electron transfer.

[00:49:01]Answer.

[00:49:10]Answer.

[00:49:24]of electron.

[00:49:33]Transfer of five electron. Sir Aidus 8 + 8 + 7. Very good.

[00:50:04]Very good.

[00:50:14]oxidation state option eight correct very good oxidation number in H N C2 L respectively question number second question.

[00:50:53]Answer [clears throat] A B C.

[00:51:06]Option D.

[00:51:08]Option D.

[00:51:14]Very good answer.

[00:51:28]Very good. Very good.

[00:51:44]self service Generally metal hydide oxidation number one C2 + 2 minus option D.

[00:52:39][clears throat] I think.

[00:52:50]Oh, oxygen has the oxidation state of plus two in the compound compound oxygen plus oxidation state.

[00:53:05]H2O CO2 H2 F2 ABC.

[00:53:42]Yes.

[00:53:45]Basic class.

[00:56:38]Very good. Very good.

[00:56:51]H2O H2P example.

[00:57:17]What's >> [clears throat] >> decomposition reduction reaction.

[00:57:57]C3rid more elect 4 - 2 + Oxygen calcium.

[00:59:06]Still it is a decomposition.

[00:59:11]Example prime example calcium carbon I Yes.

[00:59:47]Yes.

[00:59:55]Next.

[00:59:56]Displacement.

[00:59:58]Displacement. Disactional disal more reactive metal to less metal dismental reactive. for reactive metal. Fore displacement reactional disment. reaction.

[01:01:54]Metal displacement reaction.

[01:02:01]Second, second point.

[01:02:20]Say more powerful less powerful Okay. Double double displacement.

[01:03:11]Nonmetal disalment.

[01:03:16]Example plus CO4 plus C4.

[01:03:30]Sorry. Zn4 plus CN strong less powerful. less powerful.

[01:03:58]Aglment.

[01:04:24]Double displacement.

[01:04:43]Either double Double displacement.

[01:05:15]Then double [clears throat] Examples Na H N His Next disproportion. reaction.

[01:06:17]Same type of This Basically both same element numberated.

[01:07:26]type of variety of Number CL2 CL minus Cl3 minus dispose plus rection.

[01:08:36]Say both.

[01:09:06]Hello.
