MCQ
Indicate the nature of bonding in $CC{l_4}$ and $Ca{H_2}$
  • ✓
    Covalent in $CC{l_4}$ and electrovalent in $Ca{H_2}$
  • B
    Electrovalent in both $CC{l_4}$ and $Ca{H_2}$
  • C
    Covalent in both $CC{l_4}$ and $Ca{H_2}$
  • D
    Electrovalent in $CC{l_4}$ and covalent in $Ca{H_2}$
✓

Answer

Correct option: A.
Covalent in $CC{l_4}$ and electrovalent in $Ca{H_2}$
a
$Ca ^{+2}$ forms two ionic bonds with $H ^{-}$ion. While in $CCl _4$, carbon forms $4$ covalent bonds with four hydrogen atoms.
