NaCl and CaCl2 contains only ionic bond between Na+ and Cl- ions (N a+ C l-) and between Ca2 + and Cl- respectively while rest other compounds have covalent bonds as follows <img class="img-fluid question-image" alt="Solution" src="https://cdn.tardigrade.in/q/nta/c-habwpxqxjcnp.png" />

Q. Which of the following compounds contains no covalent bond(s)?

$N a Cl, P H_{3}, O_{2}, B_{2} H_{6}, H_{2} S O_{4}, C a C l_{2}$

$N a Cl, B_{2} H_{6}$

$N a Cl, B_{2} H_{6}, P H_{3}$

$N a Cl, H_{2} S O_{4}$

NaCl $, C a C l_{2}$

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
