The compound 1, 2 -butadiene has

only sp hybridized carbon atoms
only sp² hybridized carbon atoms
both sp and sp² hybridized carbon atoms
sp, sp² and sp³ hybridized carbon atoms

Solution

sp
sp²
sp³
dsp²

Solution

Hybridisation of N = ½ [5 +3 +0 – 0] = 4 hence sp³.

Which of the following has the shortest C – C bond length?

C₂H₅OH
C₂H₆
C₂H₂
C₂H₄

Solution

Because of the triple bond the carbon - carbon bond distance in ethyne is shortest.

The bond angle between two hybrid orbitals is 105°. The percentage of s-character of hybrid orbital is between

50 - 55%
9 - 12%
22 - 23%
11 - 12%

Solution

Solution

Which of the following set contains species having same angle around the central atom?

SF₄, CH₄, NH₃
NF₃, BCl₃, NH₃
BF₃, NF₃, AlCl₃
BF₃, BCl₃, BBr₃

The hybrid state of Sin SO₃ is similar to that of

C in C₂H₂
C in C₂H₄
C in CH₄
C in CO₂

Solution

The true statements from the following are
1.PH₅ and BiCl₅ do not exist
2.pπ- dπ bond is present in SO₂
3.Electrons travel at the speed of light
4.SeF₄ and CH₄ have same shape
5.\(I_{3}^{+}\) has bent geometry

1, 3
1, 2, 5
1, 3, 5
1, 2, 4

Solution

SeF₄ has distorted tetrahedral geometry while, CH₄ hastetrahedral geometry.

The trigonal bipyramidal geometry is obtained from the hybridisation :

dsp³ or sp³d
dsp² or sp²d
d²sp³ or sp³d²
None of these

Solution

According to VSEPR theory, trigonal bipyramidal geometry results from sp³d or dsp³ hybridisation.dsp² hybridisation results in square planar geometry,while d²sp³ leads to octahedral shape.

Amongst the following, the molecule/ionthat is linear is:

SO₂
CO₂
\(ClO_{2}^{-}\)
\(NO_{2}^{-}\)
