Amines — Chemistry STD 12 Science — Question

Assertion $A:$ Butan$-1-$ol has higher boiling point than ethoxyethane.

Reason $R:$ Extensive hydrogen bonding leads to stronger association of molecules.

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

1. $ \mathrm{Cu}^{+} \rightarrow \mathrm{Cu}^{2+}+\mathrm{Cu} $
2. $ 3 \mathrm{MnO}_4{^-}+4 \mathrm{H}^{+} \rightarrow 2 \mathrm{MnO}_4{^-}+\mathrm{MnO}_2+2 \mathrm{H}_2 \mathrm{O} $
3. $ 2 \mathrm{KMnO}_4 \rightarrow \mathrm{K}_2 \mathrm{MnO}_4+\mathrm{MnO}_2+\mathrm{O}_2 $
4. $2 \mathrm{MnO}_4{^-}+3 \mathrm{Mn}^{2+}+2 \mathrm{H}_2 \mathrm{O} \rightarrow 5 \mathrm{MnO}_2+4 \mathrm{H}^{+} $

$Zn ^{2+}+2 e ^{-} \rightarrow Zn ; E ^{\circ}=-0.760 \,V$

$Ag _{2} O + H _{2} O +2 e ^{-} \rightarrow 2 Ag +2 OH ^{-} ; E ^{\circ}=0.344 \,V$

If $F$ is $96,500 C mol ^{-1}$ $\Delta G ^{\circ}$ of the cell will be $....$ (In $kJ mol ^{-1}$)
