MCQ
Which of the following is not formed by the ozonolysis of $o-$xylene
- AGlyoxal
- ✓Ethyl glyoxal
- CDimethyl glyoxal
- DMethyl glyoxal
✓
Answer
Correct option: B.
Ethyl glyoxal
b
$o$-Xylene has two resonance structures. Hence, on ozonolysis of $o$-xylene, a mixture of methylglyoxal, $1,2$-dimethylglyoxal and glyoxal will be produced.
