(d) Ethanol > \(n-\) propanol > \(n-\) butyl alcohol Solubility of alcohols in water decreases as the size of alkyl group increases because tendency to form hydrogen bonding decreases.

Which one of the following will most readily be dehydrated in acidic condition
1
2
3
4
Explanation:
(a) Aldols (\(\beta-\) hydroxy aldehydes or \(\beta-\) hydroxy ketones) readily undergo dehydration to form \(\alpha,\beta-\) unsaturated aldehydes or ketones.

Which of the following compounds will be most easily attacked by an electrophile
1
2
3
4
Explanation:
(c) Phenol is most easily attacked by an electrophile because presence of \(-OH\) group increases electron density at \(o-\) and \(p-\) positions.
(d) Ethanol > \(n-\) propanol > \(n-\) butyl alcohol Solubility of alcohols in water decreases as the size of alkyl group increases because tendency to form hydrogen bonding decreases.
