Worked practice questions

According to the octet rule, atoms achieve stability by attaining an outer shell configuration of:

  1. ns² np²
  2. ns² np⁴
  3. ns² np⁶
  4. ns¹ np⁵
Show answer and solution

Correct answer: C. ns² np⁶

The octet rule states atoms achieve stability by attaining a noble-gas outer shell of **eight valence electrons (ns² np⁶)**. Helium is the exception with a duplet.

Glucose in open-chain form has a:

  1. Ketone group at C-2, like fructose has in the same molecule
  2. Aldehyde group at C-1, with four chiral carbons in the chain
  3. Carboxylic acid group at C-1, with five hydroxyl groups
  4. Ester group at C-6, with a cyclic structure in solid form
Show answer and solution

Correct answer: B. Aldehyde group at C-1, with four chiral carbons in the chain

Glucose open chain: aldehyde at C-1 and -OH at C-2 to C-5 with -CH$_2$OH at C-6; four chiral C.
