Question

Hi please help me with this question

Answer 1

Answer:

G : pent-2-ene

H : H2o

I : pent-1-ene

Explanation:

The OH would combine with H from H-O4SH

Then the O attached to the carbon would get detached taking the electrons with it, leaving carbon an positively charged.

The OH now combined with H-O4SH would take the H away from the acid forming H2O and (O4SH)-

The negative ion of (O4SH)- would then take the H from positively charged C forming the sulphuric acid back. It does not take the electrons with it*

Which is why the carbon can then form a double bond with the excess electron (2). the major product would be pent-2-ene and minor would be pent-1-ene.

This is because pent-2-ene is more stable than pent-1-ene. (Due to secondary carbon and primary carbon factor)

This is the whole backstage story though.
