Per NCERT, what does it mean when two atoms are joined by a DOUBLE bond?
AThey share one electron
BThe two atoms share TWO PAIRS of electrons (four electrons total) — depicted by two lines (e.g. O=O in O₂)
CThey transfer two electrons
DThey are ionic
Answer & Solution
Correct answer: B. The two atoms share TWO PAIRS of electrons (four electrons total) — depicted by two lines (e.g. O=O in O₂)
Per NCERT §9.4.1, double bond = 2 shared pairs (4 electrons). Single bond = 1 shared pair. Triple bond = 3 shared pairs.
