Answer:
Aldehyde and ketone both react with alcohols (2 equivalent) in the presence of acid catalyst to give acetals.
Explanation:
Alcohols are poor nucleophiles and so protonation of the carbonyl oxygen used to make the carbonyl carbon a stronger electrophile. Addition of the first equivalent of alcohols gives a hemiacetal,
Addition of the second equivalent of alcohol is accompanied by loss of one molecule water to yield the produce acetal.
Answer:
Measure 74.2 g Na2CO3 and add H20 until the final homogeneous solution has a volume of 7.00 L
Explanation:
The best procedure is
Mole of
= 0.700 mol
The mass of
= 74.2 g
So as per the above calculation, the option 3 is correct as the solution volume is 7.00 L so the same is to be considered
hence, all other options are wrong
