Question

What are likely formulas for the following molecules?

 (a)  NH_?OH (b) AlCl_?(c) CF₂Cl (d)CHO_?  

(b)

Step-by-Step Solution

Answer

Answer

The chemical formula is AlCl₃ .

Step 1: Chemical formula for the aluminium compoun d

The chemical element aluminium is in group 3A of the periodic table, and chlorine is in group 7A, which requires a single electron to attain octet.

Step 2:Fundamentals about aluminium

Aluminum has three valence electrons, and chlorine has one valence electron, so aluminum bonds to three chlorine atoms— AlCl₃.

Step 3:The chemical formula for the molecule

Thus, the possible formula for the given compound is AlCl₃.
