Chemical Bonding and Molecular Structure Questions

Multiple choice

Which of the following is/are polar covalent compound/s?

  1. HCl

  2. Ammonia

  3. Urea

  4. Both 1 and 2
Reveal answer Fill a bubble to check yourself
D Correct answer
Explanation

Both HCl (hydrogen chloride) and ammonia (NH3) are polar covalent compounds due to the electronegativity difference between the bonded atoms. Since both are polar, option D is the correct choice.

Multiple choice

The ionic compounds are made up of ________.

  1. positive ions

  2. negative ions

  3. positive and negative ions

  4. None of these
Reveal answer Fill a bubble to check yourself
C Correct answer
Explanation

Ionic compounds are formed by the electrostatic attraction between positively charged ions (cations) and negatively charged ions (anions).

Multiple choice

Which of the following is not a covalent compound?

  1. NaCl

  2. Glucose

  3. Naphthalene

  4. Iodine
Reveal answer Fill a bubble to check yourself
A Correct answer
Explanation

NaCl (sodium chloride) is an ionic compound formed by the transfer of an electron from sodium to chlorine. Glucose, naphthalene, and iodine are all covalent compounds.
