The p-isomer of dichlorobenzene has higher melting point than o- and m-isomer. — Chemical Bonding Chemistry Question

💡 Solution & Explanation

Step 1: Compare the bond angles: H2O (104.5°), F2O (~103°), Cl2O (~111°), and H2S (~92°). Step 2: In Cl2O, the chlorine atoms are very large and electronegative, causing strong steric and electrostatic repulsions between the two bulky chlorine atoms. Step 3: This severe steric crowding forces the Cl-O-Cl bond angle to open up significantly (~111°), making it the largest among the options. Thus, option (c) is correct.
