Per NCERT §9.5.1, the formula of carbon tetrachloride (covalent compound) obtained by criss-cross of valencies is which?
AC₂Cl₂
BCCl₄ (C valency 4, Cl valency 1; crossed over gives CCl₄)
CC₄Cl
DCCl
Answer & Solution
Correct answer: B. CCl₄ (C valency 4, Cl valency 1; crossed over gives CCl₄)
Per NCERT §9.5.1 Examples, C(4) + Cl(1) → CCl₄. Subscripts come from cross-over of valencies.
