Chapter 1: Q.1-1-24b (page 27)

What are likely formulas for the following molecules?

(a) NH?OH (b) AlCl?(c) CF2Cl(d)CHO?

(b)

Short Answer

Expert verified

Answer

The chemical formulais AlCl3.

Step by step solution

01

 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.

02

Step 2:Fundamentals about aluminium

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

03

Step 3:The chemical formula for the molecule

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