▶Two properties of Covalent bond :

✔It is formed by sharing of electrons .

✔It is directional .

____________________________________

▶π bond is weaker than sigma bond a because the extent of overlapping in the formation of π bond is less ✔

___________________________________

▶He2 does not exist because it's bond order is zero ✔


___________________________________


▶dz2 is involved in sp3 d hybridisation.✔

__________________________________


▶Three Covalent bond and one co ordinate bond are present in NH4+✔

____________________________________


▶Bond order is related to the bond strength and bond length because when bond order Increase, bond strength Increases but bond length decreases.✔

Answer 2

i)covalent bondC2H2 , CCL4 , NH3 , CO2 and C5H8..

ii)Because the extent og overlapping is less in pi bons due to lateral overlapping wheread in formation of sigma bond the extent of overlapping is more because it is along the internuclear axis.

ii)because He is doublet .

,4)dz2 is d orbitals is involved in sp3 d hybridization

5)covalent bond

6)bond order inverse proportion to bond length and directly proportional to bond strength.
