Among the following compounds, the number of compounds that give positive iodoform test is-----.
i) `CH _(3) - CH (OH ) - CH _(3)`
ii) `CH _(3) - overset( O) overset (||) (C) - CH _(3)`
iii) `CH _(3) - CH _(2) - CHO`
iv) `CH _(3) - CH _(2) - OH`
v) `CH _(3) - CH _(2) - overset( O ) overset( ||) (C) - CH _(2) - CH _(2) `
vi) `CH _(2) - CHO `

Text Solution

Verified by Experts

The correct Answer is:
4

Compounds containing `CH_(3) - CO-` group give iodoform test. In addition to this, ethanol and alcohols having formula
`H_(3)C - CH(OH) - R` give positive iodoform test.
