Can anybody please explain questions 5,13,23,36 and 39?
The problems are as follows:
In 5 why can't A be correct as it is symmetrical.
In 13 why can't A(Mg) be the answer as when it dissolves the pH is around 6.5 which suggests hydrolysis.
In 23 why can't D(180) be the answer as the chain is like -C-C-C-C-C- which shows the C-C-C bond to be 180.
In 36 why is 2(NH3 behaves as a base) is correct.
In 39, actually I don't get a single point!
Thanks in advance and please try these questions out if possible as they are confusing and they might even help you out!
