Which one of the following mono-enes does not exhibit geometrical isomerism?
1 $\mathrm{C}_{4} \mathrm{H}_{8}$
2 $\mathrm{C}_{3} \mathrm{H}_{6}$
3 $\mathrm{C}_{5} \mathrm{H}_{10}$
4 $\mathrm{C}_{8} \mathrm{H}_{16}$
Explanation:
The $\mathrm{C}_{3} \mathrm{H}_{6}$ shows geometrical isomerism. It must have restricted rotation around double bond \& substituent attached to the ligand must be different It show G.I.

Least stable conformer of cyclohexane is
1 Chair
2 Boat
3 Twist boat
4 Planar hexagon
Explanation:
The least stable conformer of cyclohexane is boat form because it has high potential energy. The order of stability of any compound depend upon its interaction of its 1-3, 1-4, H-H bonding higher number instruction so energy will be high lower will be the stability.

n-pentane and iso-pentane are the examples of which isomerism?
1 Geometrical
2 Optical
3 Chain
4 Position
Explanation:
(C) : From above structure we can say that it is chain isomer because there is no change of carbon in parent chain.
