Assertion : Carbanions like ammonia have pyramidal shape. Reason : The carbon atom carrying negative charge has an octet of electrons.

Assertion :Kinetic energy and momentum of ideal gas molecules are conserved during intermolecular collision. Reason :Collision among real gas molecules is inelastic.

Assertion : The pressure of a gas is inversely proportional to the volume at constant temperature and n. Reason : The gas volume is directly proportional to n at constant temperature and pressure.

Which of the following is a correct plot of the volume of fixed amount of ideal gas as a function of temperature (at constant pressure) ? (a) (b) (c) (d)

Assertion:CH₄, CO₂ has value of Z (compressibility factor) less than one at 0ºC. Reason :Z < 1 is due to the attractive forces dominate among the molecules.
