Question

What are likely formulas for the following molecules?

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

(b)

Short answer

Answer

The chemical formulais AlCl₃.

Step-by-step solution

 Chemical formula for the aluminium compound

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.
