The correct statements from following are:

A. The strength of anionic ligands can be explained by crystal field theory.

B. Valence bond theory does not give a quantitative interpretation of kinetic stability of coordination compounds.

C. The hybridization involved in formation of $$\left[\mathrm{Ni}(\mathrm{CN})_4\right]^{2-}$$ complex is $$\mathrm{dsp}^2$$.

D. The number of possible isomer(s) of cis- $$\left[\mathrm{PtCl}_2(\mathrm{en})_2\right]^{2+}$$ is one

Choose the correct answer from the options given below:

Given below are two statements: One is labelled as Assertion A and the other is labelled as Reason R:

Assertion A: Alcohols react both as nucleophiles and electrophiles.

Reason R: Alcohols react with active metals such as sodium, potassium and aluminum to yield corresponding alkoxides and liberate hydrogen.

In the light of the above statements, choose the correct answer from the options given below:

The product (C) in the below mentioned reaction is :

$$\mathrm{CH}_3-\mathrm{CH}_2-\mathrm{CH}_2-\mathrm{Br} \xrightarrow[\Delta]{\mathrm{KOH}_{(\text {alc) }}} \mathrm{A} \xrightarrow{\mathrm{HBr}} \mathrm{B} \xrightarrow[\mathrm{KOH}_{(\mathrm{aq})}]{\Delta} \mathrm{C}$$
