Hello everyone that's of this question in this question we have to find out which reactants can be used with the grignarge reagent to produce the given products.
00:12
So first one is this it is a primary it is primary alcohol so we need to take formaldehyde so for aldehyde and cyclohexyl hexyl magnesium magnesium halide that is grignard reagent here will form this compound.
00:45
Let's see the reaction.
00:47
This is cyclohexyl, sorry, cyclohexyl magnesium halide and it is reacting with formaldeide.
00:59
So we have a negative and a positive charge here and here we have mg plus.
01:07
So this will attack on the ring.
01:12
So we will get the product as big.
01:17
With the intermediate this is the intermediate o negative mgbr and on adding water to it or acidified water to it it will give us the product.
01:38
So for the b let's check what is the reaction and what are the reactants.
01:46
So here we have oh and it is a tertiary alcohol it is tertiary alcohol.
01:59
It is tertiary alcohol.
02:02
Call and so we will take ketone with grignard reagent.
02:14
So let's see the reaction...
