C

D
Question 2
1 / -0

A should be:

A
$$ \mathrm { B } _ { 2 } \mathrm { H } _ { 6 } - \mathrm { THF } / \mathrm { DCOOH } $$

B
$$ \mathrm { B } _ { 2 } \mathrm { H } _ { 6 } - \mathrm { THF } / \mathrm { DCOOD } $$

C
$$ \mathrm { B } _ { 2 } \mathrm { D } _ { 6 } - \mathrm { THF } / \mathrm { HCOOH } $$

D
$$ \mathrm { B } _ { 2 } \mathrm { D } _ { 6 } - \mathrm { THF } / \mathrm { HCOOD } $$

Solution
Question 3
1 / -0

In the given reaction, the product 'Y' is:

A
a positive isomer of X.

B
identical to X.

C
chain isomer of X.

D
an oxidation product of X.

Solution

In presence of $$B_2H_6, THF$$, the given alkene undergoes Anti-Markownikoff's addition.
In this reaction, $$t-BuO^{\circleddash}K{\circleddash}$$ is a hindered base abstract proton from a less sterically hindered site. So, $$(Y)$$ product is formed, which is a chain isomer of $$(X)$$.

$$Mg^{2+}$$

C
$$Al^{3+}$$

D
$$P^{5+}$$
