BCl3 is a planar molecule, while NCl3 is pyramidal, because
N-Cl bond is more covalent than B-Cl bond
nitrogen atom is smaller than boron atom
B-Cl bond is more polar than NCl bond
BCl3 has no lone pair of electrons but NCl3 has a lone pair of electrons.
B.
nitrogen atom is smaller than boron atom
D.
BCl3 has no lone pair of electrons but NCl3 has a lone pair of electrons.
BCl3 has trigonal planar structure due to 3 bond pairs in the valence shell of boron where as NCl3 has distorted tetrahedral structure due to one lone pair and three bond pair in the valence shell of nitrogen.
The correct sequence of hybridisation of methane, ethene and acetylene is :
sp, sp2, sp3

sp3, sp2, sp
sp3, sp, sp2
Which of the following diatomic molecular species has only π bonds according to Molecular Orbital Theory?
N2
C2
Be2
O2
The manganate and permanganate ions are tetrahedral, due to :
There is no π-bonding
The π- bonding involves overlap of p-orbitals of oxygen with p-orbitals of manganese.
The π-bonding involves overlap of d-orbitals of oxygen with d-orbitals of manganese
The π-bonding involves overlap of p-orbitals of oxygen with d-orbitals of manganese
Assertion : Bond lengths of P-Cl bonds in gaseous PCl5 and solid PCl5 are not equal.
Reason : Because in solid state two PCl5 molecules are associated.
If both assertion and reason are true and reason is the correct explanation of assertion.
If both assertion and reason are true but reason is not the correct explanation of assertion.
If assertion is true but reason is false.
If both assertion and reason are false.
