Question

Which of the following contains a total of eight carbons?
a.) nonane
b.) dimethylpropane
c.) 2-methyl-4-heptyne
d.) 4-methyl-decane

Answer 1

i'm thinking c. but idk for sure. hope it helps :) good luck

Answer 2

yeah im pretty sure it's c

Answer 3

2-methyl-4-heptyne has a molecular formula of C8H14, so that would be an excellent choice.

Answer 4

nonane = 9 carbons you should just draw each structure out and see let's do that

Answer 5

This is asking for which carbon contains a total of 8 carbons. so there must be 8 carbons in total

let's look at the naming system first.

2-methyl-4-heptyne

hep = 7 carbons in our chain. this means our longest carbon chain is 7 carbons long.

2-methyl, means the methyl group CH3 is on carbon 2.

yne means we have a triple bond, and 4 tells us that our triple bond is between carbons 4-5.

take a look at what I wrote below

Answer 6

we first start with our longest chain. hep means there are 7 carbons in total.

Answer 7

then we fill in the substituents 2-methyl means the methyl group ch3 goes at carbon 2 and 4 yne means a triple bond goes between carbons 4 and 5
