The statement "The electrons in the p bonds of alkynes are more tightly held than those of alkenes" is not true. In fact, the opposite is true - the electrons in the p bonds of alkynes are less tightly held than those of alkenes. This is because alkynes have a higher electron density in their p bonds due to the smaller bond length, making them more reactive and prone to addition reactions.
