[00:00:00]top 30 30 named reactions okay now and I'm doing this session keeping that in mind so short notes okay so for that reason so that you can have it as a notes so first and foremost reaction is all condensation all condensation first Important reaction condensation.

[00:00:34]Condensation alpha hydrogen reaction or ketones.

[00:00:49]Make sure that ketone alpha hydrogen then it can undergo all condensation and reagent we are taking a base. So alihides or ketones with a base all condensation alihide ketone concentrated hydrogen condensation condensation condensation because alihide or ketone is my starting reactant. Then alpha hydrogen. So functional group then immediate next carbon alpha and alpha hydrogen alpha hydrogen.

[00:02:03]So alihide ketone is there and alpha hydrogen's are there. So condensation unsaturated ketone into the alpha beta unsaturated ketone.

[00:02:29]So I'm writing for you here. So CH3 double bond will be taking two molecules. So double bond CH3.

[00:02:56]So CH3 double bond or CH3 E compound.

[00:03:01]Okay. Now next compound compound ketone group sameone group. So what do you have? So CH3 COH3 next inco3 and you have one more CH3 samele.

[00:03:26]Okay.

[00:03:34]Double bond satisfied.

[00:03:41]So watercule double bond simple let it be CH3 double bond of CH3 in presence of a base. Okay.

[00:04:10]or hydrogen condensation. So first molecules react. So this is one molecule inco3 double bond CH3.

[00:04:28]Okay. So combine I'm writing this as one carbon. So double bond either carbon.

[00:04:38]Next. Earbon key.

[00:04:41]Earbon O CH3. So Earon O CH3 CH3.

[00:04:51]Correct. So CH3 CH3 CH3 CH3.

[00:05:05]So convert this into Oygen you'll get a double bond that's your answer alpha beta unsaturated ketone simple that's it so this is the first reaction all condensation so all condensation Next reaction reaction we'll be using the caniserero reaction for when there is no alpha hydrogen so alpha hydrogen but reaction reaction correct so reaction same compound alihide or ketonehides alpha hydrogen and with respect to a base reaction.

[00:06:21]If you see this benzaldihide MOLECULE NEXT two products alcoholic acid.

[00:07:03]So first benzene convert into acid convert it into acid. OKAY.
