Answer 1

If electronegativity difference ($\bigtriangleup E_n$) between bonded atoms is between 0 to 0.4 , then it is non polar covalent bond.

If electronegativity difference ($\bigtriangleup E_n$) between bonded atoms is between 0.5 to 2.0 , then it is polar covalent bond.

If electronegativity difference ($\bigtriangleup E_n$) between bonded atoms is between 2.1 to 4 , then it is ionic bond.

a)

$\bigtriangleup E_n$ for H-Li= 2.1-1.1 =2 ,polar bond

b)

$\bigtriangleup E_n$ for C-O =3.5-2.5 =1.0 polar bond

c)

$\bigtriangleup E_n$ for B-Cl=3.0-2.0=1.0 , polar bond

d)

$\bigtriangleup E_n$ for Li-O =3.5-1.1 = 2.4 ,ionic bond

e)

$\bigtriangleup E_n$ for H-P= 2.1-2.1 =0 , non polar bond

answer is (e)
