Explanation

Hydrocarbons do not have a tendency to form hydrogen bonding.

Because they lack highly electronegative atoms like oxygen or nitrogen that are necessary for hydrogen bonds.

In contrast, carboxylic acids, ammonia, and ethyl alcohol can all engage in hydrogen bonding due to their functional groups.

Explanation

To boil water at 110°C, the external pressure must be higher than normal atmospheric pressure (760 torr), typically in the range of 760 - 1200 torr. 

This increased pressure raises the boiling point of water above its standard boiling point of 100°C.

Explanation

Real gases show deviation from ideal behavior at low temperature and high pressure.

Due to increased intermolecular forces and reduced volume available for gas molecules, which contradicts the assumptions of ideal gas behavior.

Explanation

The correct ideal gas equation is PV = nRT.

Where P is pressure, V is volume, n is the number of moles, R is the ideal gas constant, and T is temperature in Kelvin.

This equation relates these properties for an ideal gas under various conditions.
