Name each compound.

Question

/\/\NH2 (that's suppose to be a line diagram...) I got 1-pentanamine, but that's wrong.

CH3CH2-O-CHCH2CH3
.....................|
..................CH3

I'm not sure how great this will turn out, but there's supposed to be a CH3 branching off of the C directly to the right of the O in the main chain.
I thought it might be something like 3-ethyl-ethoxypropane but that's way off.

Answer 1

..........CH3...................................CH3
............|..........................................|
CH3 -- C -- C =(triple bond)= C -- C -- CH3
............|..........................................|
...........CH3....................................CH3

Can't get this one either...

Answer 2

longest carbon chain six carbons, triple bond on number 3 carbon, dimethyl on carbon 2,and5 (I think,the drawing is garbled).



so 2,2,5,5-tetramethyl-3-hexyne

Answer 3

I don't follow the first diagram. The -O- makes it what....?
