how would i draw this compound?

Question

How would I draw 1-chloro-1-ethylcyclopentane?

Answer 1

Ah, good old organic naming.

I always start at the back of the name and work forward to the front.

ending: -ane This means there are only single bonds present. Easy enough.

-pentane This means there is a 5 carbon chain with the bonds mentioned

-cyclopentane This menas those 5 carbons are in a ring shape.

This is where I would start then. Draw the 5 carbons in a ring. Should look like a pentagon.

Next 2 things are the additional things coming off of the ring.

1-ethyl: Means there is a CH2CH3 group coming off one of the carbons.

1-chloro: Means there is a Cl coming off the same carbon as the CH2CH3.

In the end, you'll get a structure that has a Cl and a CH2CH3 coming off one carbon in a 5 member ring. The other carbons are understood to have hydrogens around them to fill their 4 available bonding sites.

Answer 2

Yeah, I'm not drawing that here. But it should be a 5 carbon ring (cyclopentane) with one carbon in the ring having both a Cl and a 2 carbon chain (ethyl) attached to it. And of course, the requisite hydrogens to fill it out.

Answer 3

You can find the structure of 1-chloro-1-ethylcyclopentane on p. 106 of this document (Practice Problem 4.1): http://www.wadsworthmedia.com/marketing/sample_chapters/0495012033_ch04.pdf .
