There are four different compounds with the formula C7H16, each of which can form only three different monochlorides as a result of free radical halogenation. (Ignore stereochemistry.) The choices are….
3-ethylpentane
3,3-dimethylpentane
2,3-dimethylpentane
2,4-dimethylpentane
2,2-dimethylpentane
3,4-dimethylpentane
2-ethylpentane
2,3,3-dimethylbutane
2,2,3-trimethylbutane
I picked 4 and was wrong. Really need this one right too. If you could supply and explaination that would be great. Thank You!

They are 3 girls- 10,10 and 9 months and 1- 9 year old boy…The baby is easy to entertain and my biological 10 year old will keep herself busy by reading or whatever. The other kids are my full time step kids… the girl “is bored” and will just sit there and stare at me while I am doing housework or making dinner. The boy is content with just sitting there and playing the gameboy or computer. We are VERY short on money this summer since it was unexpected that I would be quitting work to stay home let alone that they would come to live with us full time.
Any ideas would be great. We have done the museums on free day, the zoo on cheap day, the library, the free water sprinkler park…
I don’t mean to gripe, but…
Should I have to “find” things for the 10 and 9 year old to do while I am making dinner and such? Shouldn’t they at least be able to entertain themselves with all the stuff they have?
