Explanation / Answer

answer for question no 1

for HF electronegativity difference is high and the type of bond formed is more ionic

for CrO electronegativity difference is low and the type of bond formed is more covalent

for Br2 electronegativity difference is zero and the type of bond formed is covalent

for NaCl electronegativity difference is high and the type of bond formed is more ionic

for question no 2

a) ionic bond

b) covent bond

c) ionic bond

d) ionic bond
