General Properties Of Organic Compounds - Quiz

About This Quiz

This quiz is intended for testing the students' knowledge on the general properties of organic compounds such as polarity, solubility, boiling points, combustibility, stability, compatibility, acidity, and basicity. Please view the video before taking the quiz.

2.

Which of the following compounds is readily to dissolve in water?
- Pentane
- Pentanol
- Pentanoic acid
- Sodium pentanoate
- Penthouse
Correct Answer

A. Sodium pentanoate

Explanation

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

1
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
Correct Answer

A. D > b > a > c

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
Correct Answer

A. Cooking oil, gasoline, paraffin

Explanation

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

Rate this question:
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
Correct Answer

A. NaOH & MeOH

Explanation

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

Rate this question:
6.

Which of the following compounds is likely to have the lowest flash point?
- Gasoline
- Cooking oil
- Pentane
- Rubbing alcohol
- Carbon dioxide
Correct Answer

A. Pentane

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.

Rate this question:
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?
- Sodium carbonate
- Lithium Cyanide
- Carbon Monoxide
- Carbonic acid
- Plastic
Correct Answer

A. Plastic

Explanation

Plastic usually contain 70-98% of carbon.
