Question

Trichloroacetaldehyde was subjected to Cannizzaro'* reaction by using NaOH. The mixture of the products contains sodium thrichlorethanol ion and another compound. The other compound is

(a) 2, 2, 2-trichlorethanol

(b) trichloromethanol

(c) 2, 2, 2-trichloropropanol

(d) chloroform

Answer 1

Correct Option(a) 2, 2, 2-trichlorethanol

Explanation:

Cannizzaro'* reaction is given by aldehydes (RCHO) lacking H at α-carbon (as in HCHO). With NaOH, there is formation of acid salt (RCOO-) by ocidation and alcohol (RCH2OH) by reduction.
