The compound which does not respond to iodoform test is

Options

ACH ₃- CHO
BCH ₃ CH ( OH ) CH ₃
CC ₂ H ₅- CO - C ₂ H ₅
DC ₆ H ₅ COCH ₃

Correct answer

C. C ₂ H ₅- CO - C ₂ H ₅

Step-by-step solution

Iodoform test is used to identify methyl ketones. It is used for the detection of ketones and aldehydes having an alpha methyl group. As, option (c) does not have any methyl group, it does not respond to iodoform test.
