Question

Which of the above compounds contain at-least on secondary alcohol?

• A. $\left(I\right),\left(II\right),\left(III\right),\left(IV\right)$
• B. $\left(I\right),\left(III\right),\left(V\right)$
• C. $\left(I\right),\left(II\right),\left(IV\right),\left(VI\right)$
• D. $\left(I\right),\left(II\right),\left(III\right)$

Answer 1

The correct option is B $\left(I\right),\left(III\right),\left(V\right)$

$2^o$ alcohols are those alcohols, in which $-OH$ group is attached to $2^o$ carbon $\underset{2^{o}carbon}{(C-\stackrel{\ast }{C}H-C)}$.

Hence, the correct option is B.
