Question

1. the formula c₂h₅ch(cooh)₂ contains (1pts) 7 hydrogen atoms 4 carbon atoms 8 hydrogen atoms 2 oxygen atoms

Explanation:

Step1: Count carbon atoms

Carbon count: $2 + 1 + 1 + 1 = 5$ (from $\text{C}_2\text{H}_5$, $\text{CH}$, and two $\text{COOH}$ groups)

Step2: Count hydrogen atoms

Hydrogen count: $5 + 1 + 2 = 8$ (from $\text{C}_2\text{H}_5$, $\text{CH}$, and two $\text{COOH}$ groups)

Step3: Count oxygen atoms

Oxygen count: $2 \times 2 = 4$ (two $\text{COOH}$ groups, each with 2 O)

Step4: Match correct option

Compare counts to given choices.

Answer:

$\boldsymbol{\square}$ 8 hydrogen atoms
