The restricted rotation about carbon-carbon double bond in 2- butane is due to:
1 Overlap of one s-and one $\mathrm{sp}^{2}$-hybridized orbitals
2 Overlap of two $\mathrm{sp}^{2}$-hybridized orbitals
3 Overlap of one $\mathrm{p}$-and one $\mathrm{sp}^{2}$-hybridized orbitals
4 Sideways overlap of two p-orbitals
Explanation:
The restricted rotation about carbon-carbon double bond in 2-butene is due to sideways overlap of one s and one $\mathrm{sp}^{2}$ - hybridization two p-orbital's.

Which of the following will have a meso-isomer also?
1 2,3-Dichloropentane
2 2,3-Dichlorobutane
3 2- Chlorobutane
4 2-Hydroxypropanoic acid
Explanation:
(B) : - There must be more than one Assymetric Centre. - There must be plane of symmetry in a compound these two conditions are meso compound.

Which of the following contain plane of symmetry?
1 Trans-1, 3 dichloro cyclohexane
2 Trans-1, 2 dichloro cyclohexane
3 cis-1, 2 dichloro cyclohexane
4 Trans-1, 3 cyclopentane
Explanation:
Plane of symmetry only exist in a molecule when all atoms of a given molecule exist in same plane. **Plane of Symmetry** - An imaginary plane passing through molecule bisecting into two equal parts which are mirror image to each other is said to be plane of symmetry.
