1. Formic acid is produced by [S.S.C. Online Graduate Level (T-I) 31.08.2016 (Shift-III)]

Correct Answer: (c) Red ants
Solution:Formic acid is also known as methanoic acid (HCOOH). It is an organic compound found naturally in the stings of red ants, bees, scorpions, and wasps. When an ant (especially a red ant) stings, it causes intense burning. This burning is due to formic acid itself.

7. Why does carbon tetrachloride have no dipole moment? [S.S.C. Online CHSL (T-I) 18.01.2017 (Shift-II)]

Correct Answer: (b) Because of the regular tetrahedral structure
Solution:Carbon tetrachloride (CCl₄) has no dipole moment due to its regular tetrahedral structure.

8. Which one has the highest electronegativity among the following elements? [S.S.C. Online CHSL (T-I) 18.01.2017 (Shift-II)]
