Do you expect the carbon hydride of the type (CnH2n+2) to acts as Lewis acid or bases? Justify your answer
by

1 Answer

Answer :

Ans: carbon hydride of the types(CnH2n+2)are electron-precise hydrides. In other words they have exact number of electron to form covalent bonds therefore they do not show any tendency to either gain or lose electron hence they are neither Lewis acid or Lewis bases.

Would you expect the second electron gain enthalpy of O as positive, more negative or less negative than the first? Justify your answer.

Description : Would you expect the second electron gain enthalpy of O as positive, more negative or less negative than the first? Justify your answer.

Last Answer : Ans. Second electron affinity of O is largely +ve because of repulsion between negatively charged ions and second electron to be added. Energy required to overcome repulsion is more than the energy released in gaining electron, so net energy is absorbed.
