Hey Everyone I was wondering how I could write the condensed structural formula for the following organic chemicals:

Question

1. 2,3-dimethyl-2-butene

2. 4-ethyl-2-hexyne

3. 3,3,6-trimethylnonane

4. 3-ethyl-4-prophylheptane

5. 3-octanol

6. 2-methyl-2-pentene

7. 5-methyl-1-hexene

8. 2,2,4,5-tetramethylhexane

9. propanoic acid

10. 2-pentyne

Thank you so much.

Answer 1

A lot of questions for one post. What don't you understand about writing the formulas of these compounds? 3-octanol is CH3CH2CHOHCH2CH2CH2CH2CH3.
2-pentyne is
CH3C(triple bond)CCH2CH3.
Check my thinking.

Answer 2

would 1. be CH3C(CH3) Double bond C(CH3)CH3

Answer 3

or CH2 double bond C(CH3)CH(CH3)CH3

Answer 4

The basic structure is 2-butene; therefore, the double bond must go AT the 2 carbon so it's between the 2 and 3 C. 1-butene would be CH2(double bond)C etc..
So your first answer is correct.

Answer 5

Thank you

Answer 6

1. CH3C(CH3)=C(CH3)CH3
2. CH3C(triple bond)CCH(C2H5)CH2CH3
3. CH3CH2C(CH3)2CH2CH2CH(CH3)CH2CH2CH3
4. CH3CH2CH(C2H5)CH(C3H7)CH2CH2CH3
5. CH3CH2CHOHCH2CH2CH2CH2CH3
6. CH3C(CH3)=CHCH2CH3
7. CH2=CHCH2CH2CH(CH3)CH3
8. CH3C(CH3)2CH2CH(CH3)CH(CH3)CH3
9. CH3CH2COOH
10. CH3C(triple bond)CCH2CH3

Answer 7

1. CH3C(CH3)=C(CH3)CH3
2. CH3C(triple bond)CCH(C2H5)CH2CH3
3. CH3CH2C(CH3)2CH2CH2CH(CH3)CH2CH2CH3
4. CH3CH2CH(C2H5)CH(C3H7)CH2CH2CH3
5. CH3CH2CHOHCH2CH2CH2CH2CH3
6. CH3C(CH3)=CHCH2CH3
7. CH2=CHCH2CH2CH(CH3)CH3
8. CH3C(CH3)2CH2CH(CH3)CH(CH3)CH3
9. CH3CH2COOH
10. CH3C(triple bond)CCH2CH3

Answer 8

1. CH3C(CH3)=C(CH3)CH3
2. CH3C(triple bond)CCH(C2H5)CH2CH3
3. CH3CH2C(CH3)2CH2CH2CH(CH3)CH2CH2CH3
4. CH3CH2CH(C2H5)CH(C3H7)CH2CH2CH3
5. CH3CH2CHOHCH2CH2CH2CH2CH3
