Re: Question from half yearly exam

huh?
I thort tht the cyclo - group were juz distinguished by their structural formula- in a ring- n re: the prac testing reactivities of alkanes and alkenes, cyclohexene n cyclohexane were opted since they were liquid at room temp
...
dunno tht q seems reli obscure .. does it actually relate to da syllabus?
