The product $(s)$ of the following reaction can best be described as

Identify $C$ in the following series $C_3H_7I$ $\xrightarrow[alc.]{KOH} A$ $\xrightarrow[\Delta]{NBS} B$ $\xrightarrow[alc.]{KCN} C$.

An organic compound $X$ with molecular formula $C_{11}H_{14}$ gives an optically active compound on hydrogenation. Upon ozonolysis,$X$ produces a mixture of compounds $P$ and $Q$. Compound $P$ gives a yellow precipitate when treated with $I_{2}$ and $NaOH$ but does not reduce Tollen's reagent. Compound $Q$ does not give any yellow precipitate with $I_{2}$ and $NaOH$ but gives Fehling's test. The compound $X$ is:

Which alkene on ozonolysis gives $CH_3CH_2CHO$ and $CH_3COCH_3$?

The intermediate during the addition of $HCl$ to propene in the presence of peroxide is

$but-2-yne$ is reacted separately with one mole of $H_2$ as shown below:
$\underline{ B } \xleftarrow[\text{liq } NH_3]{Na} CH_3-C \equiv C-CH_3 \xrightarrow[\Delta]{Pd/C} \underline{ A }$
Identify the incorrect statements from the options given below:
$A.$ $A$ is more soluble than $B$.
$B.$ The boiling point and melting point of $A$ are higher and lower than $B$ respectively.
$C.$ $A$ is more polar than $B$ because dipole moment of $A$ is zero.
$D.$ $Br_2$ adds easily to $B$ than $A$.
