Options

  1. AN a C l , B 2 H 6
  2. BN a C l , B 2 H 6 , P H 3
  3. CN a C l , H 2 S O 4
  4. DNaCl , C a C l 2

Correct answer

D. NaCl , C a C l 2

Step-by-step solution

NaCl and C a C l 2 contains only ionic bond between N a + and C l - ions N a + C l - and between C a 2 + and C l - respectively while rest other compounds have covalent bonds as follows
