Which will show haloform test
\(CH_{3}CH_{2}\)CHO
\(CH_{3}-CH_{2}\)-OH
\(CH_{3}-CH_{2}CH_{2}\)-OH
\(CH_{3}\)-OH

Which of the following are chain isomers? (A) \(CH_{3}CH_{2}CH_{3}\) and \(CH_{3}CH_{2}CH_{2}CH_{3}\), (B) \(CH_{3}CHCl_{2}\)and \(CH_{2}ClCH_{2}Cl\) (C) \(CH_{3}CH_{2}CH_{2}OH\) and \(CH_{3}CH_{2}OH\) (D) \(CH_{3}CH_{2}CH_{2}CH_{3}\) and \((CH_{3})_{2}CHCH_{3}\)

In the esterification reaction, the correct order of reactivity of alcohols is 1) \(CH_{3}OH>C_{2}H_{5}OH>(CH_{3})_{2}CHOH\). 2) \(CH_{3}OH>(CH_{3})_{2}CHOH>C_{2}H_{5}OH\) 3) \(C_{2}H_{5}OH>(CH_{3})_{2}CHOH>CH_{3}OH\) 4) \(CH_{3})_{2}CHOH > C_{2}H_{5}OH > CH_{3}OH\)

Among the following the number of alcohols showing iodoform test is. CH_(3)OH,CH_(3)CH_(2)OH,(CH_(3))_(2)CHOH,(CH_(3))_(3)C-OH,CH_(3)CH_(2)CH_(2)CH_(2)OH,CH_(3)CHOHCH_(2)CH_(3),CH_(3)CH_(2)CH_(2)OH,(C_(2)H_(5))_(2)CHOH,CH_(3)CHOHCH(CH_(3))_(2)

CH_3-CH_2-CH_2-CH_2-OH and CH_3-C(CH_3)_2-OH are

CH_(3)CH(OH)CH_(2)CH_(2)COOH

CH_(3)CHO+HOCH_(2)CH_(2)OH rarr
