1. What is the 1,1-dimethylethyl group, -C(CH3)3, can also be called?
2. how many methine groups are there in isopropylcyclopentane?
3. What is the total # of constitutional isomers with the formula C5H12?
Detals, please

Number one i think should be 2-methylpropane. if you draw out 1,1-dimethyethyl i get a 3 carbon chain with a methyl on carbon 2
Number two should be 2 because when you draw it out you have a cyclopentane with an isopropyl group off of the top which looks like one line with two other lines coming off of the end (bunny ears) which leaves only two carbons being CH which is what a methine group is. There should be 4 CH2 and 2 CH3 groups also.
and I am not so sure about number 3
i hope that helped at least some!

1. Tertiary butyl
2. Two CH groups: (CH3)2CH-CH< (cyclopentane)
3. Three: n-Pentane, 2-methylbutane, and 2,2-dimethylpropane.
