General Properties Of Organic Compounds

1. Which of the following compounds is an alcohol?

MeC(O)Me

MeC(O)OH

MeOH

NaOH

EtOMe

MeOH is the correct answer because it is the only compound in the given options that contains the hydroxyl functional group (-OH), which is characteristic of alcohols. MeC(O)Me is a ketone, MeC(O)OH is a carboxylic acid, NaOH is a strong base, and EtOMe is an ether.

2. Which of the following compounds is readily to dissolve in water?

Pentane

Pentanol

Pentanoic acid

Sodium pentanoate

Penthouse

d is very soluble because it's a salt. b and c are slightly soluble.

Explanation

d is very soluble because it's a salt. b and c are slightly soluble.

3. Choose the correct sequence of the following compounds in the order of decreasing acidity.
(a) water
(b) propanoic acid
(c) propylamine
(d) HCl

A > b > c > d

D > c > b > a

D > b > a > c

D > b > c > a

None of the above is correct

HCl is of course the strongest acid. Water is neutral, but more "acidic" than the propylamine base.

Explanation

HCl is of course the strongest acid. Water is neutral, but more "acidic" than the propylamine base.

4. Which of the following groups is likely to form a homogeneous solution?

Water, salt, baby oil

Water, ethanol, gasoline

Ethanol, gasoline, NaOH

Cooking oil, gasoline, paraffin

None of the above

All the three components in Group D are hydrocarbons and thus miscible.

Explanation

All the three components in Group D are hydrocarbons and thus miscible.

5. Which of the following pairs has the highest and lowest boiling points (in any order)?

Water & NaOH

NaOH & MeOH

MeOH & Water

Water & EtOH

EtOH & MeOH

NaOH is a solid and has the highest BP. MeOH has the lowest BP. Water has a higher BP than all three alcohols.

Explanation

NaOH is a solid and has the highest BP. MeOH has the lowest BP. Water has a higher BP than all three alcohols.

6. Which of the following compounds is likely to have the lowest flash point?

Gasoline

Cooking oil

Pentane

Rubbing alcohol

Carbon dioxide

Gasoline (C8-C12) is extremely flammable; but pentane has an even lower BP, and thus the FP. Carbon dioxide is a gas but not flammable.

Explanation

Gasoline (C8-C12) is extremely flammable; but pentane has an even lower BP, and thus the FP. Carbon dioxide is a gas but not flammable.

7. In general organic compounds are componds that contain carbon; however there are many exceptions. Which of the following compounds is most likely an organic compound?
