$A$ benzene derivative did not produce a white precipitate with ammoniacal silver nitrate solution (Tollens' reagent) but decolorized cold dilute alkaline $KMnO_4$ solution (Baeyer's reagent). The compound is:

What is the major product formed when propene reacts with $ICl$?

$1, 2$-dibromocyclohexane on dehydrohalogenation gives

In hydroboration-oxidation reaction $:-$
$I$. Syn addition takes place
$II$. Reaction proceeds through the formation of a cyclic transition state
$III$. Vicinal diol is obtained as a product
$IV$. Anti-addition takes place and Anti-Markovnikov rule is followed
Which of the following statement$(s)$ is/are correct $:-$

The correct statement$(s)$ for the following addition reactions is(are):
$(i)$ $trans-but-2-ene \xrightarrow{Br_2/CHCl_3} M \text{ and } N$
(ii) $cis-but-2-ene \xrightarrow{Br_2/CHCl_3} O \text{ and } P$
[$A$] ($M$ and $O$) and ($N$ and $P$) are two pairs of diastereomers
[$B$] Bromination proceeds through trans-addition in both the reactions
[$C$] $O$ and $P$ are identical molecules
[$D$] ($M$ and $O$) and ($N$ and $P$) are two pairs of enantiomers

Identify the wrong statement for the following reactions:
$R-C\equiv C-R \xrightarrow{Pd/BaSO_4} A$
$R-C\equiv C-R \xrightarrow{Na/Liq. NH_3} B$
