Hahaha yeah I wrote that too that smaller fractions are more useful than heavier ones . I read in the text book right now that alkenes are obtained from the cracking of alkanes so that could have been one of the answers but I didnt write in the exam :p The second point I wrote was to obtain hydrogen :p
i wrote that too..... it forms hydrocarbons with smaller chain lengths to be formed as fuel and to produce hydrogen

Okay I just googled and its a giant covalent structure , it says that although phophorus has a small molecular structure white phosphorus is an exception to that rule and has a giant covalent structure :D

i put it as small molecules as it is not in the same group as silicon and carbon with giant structures but is in the group of N2 which has a small structure

wait it is less negative so it increases right? :D
I didnt write about the less negative thing whatever it always confuses me , all I know is electron affinity decreases down the group because the size of the atom increases and the no. of shielding electrons increase so the incoming electron is less attracted and thus less energy is released
