MCQ
$CH_3 -CH_2 -CH=CH_2$ has hybridisation
- A$sp, sp, sp^2 , sp^2$
- B$sp^3 , sp^3 , sp^2 ,sp$
- ✓$sp^3 , sp^3 , sp^2 , sp^2$
- D$sp^3 , sp^2 , sp^2 , sp$
$S p^3$ hybridisation - single bond
$s p^2$ hybridisation - double bond
$s p$ hybridisation - triple bond
So, $CH _3- CH _2- CH = CH _2$ has hybridisation
$s p^3-s p^3-s p^2-s p^2$

$Zn ^{2+}+2 e ^{-} \rightarrow Zn ; E ^{\circ}=-0.760 \,V$
$Ag _{2} O + H _{2} O +2 e ^{-} \rightarrow 2 Ag +2 OH ^{-} ; E ^{\circ}=0.344 \,V$
If $F$ is $96,500 C mol ^{-1}$ $\Delta G ^{\circ}$ of the cell will be $....$ (In $kJ mol ^{-1}$)
$O(g) + e^- = O^-(g)$ $\Delta {H_{eg}} = - 142\,kJ\,mo{l^{ - 1}}$
$O^-(g) + e^- = O^{2-}(g)$ $\Delta {H_{eg}} = +844\,kJ\,mo{l^{ - 1}}$
This is because
