1. Assertion-Reason type
Addition of Br2 to 1–butene gives two optical isomers.
The product contains one asymmetric carbon.
2. Assertion reason type
LiCl is predominantly a covalent compound.
Electronegativity difference between Li and Cl is too small.
3. Assertion reason type
HNO3 is a stronger acid than HNO2.
In HNO3 there are two nitrogen-to-oxygen bonds whereas in HNO2 there is only one.
4. What will be the resultant pH when 200 mL of an aqueous solution of HCI (pH = 2.0) is mixed with 300 mL of an aqueous solution of NaOH (pH = 12.0)?
5. A evacuated glass vessel weighs 50.0 g when empt, 148.0 g when filled with a liquid of density 0.98 mL-1 and 50.5 g when filled with an ideal gas at 760 mm Hg at 300 K. Determine the molar mass of the gas.
