Question

multiple choice 2 points triacontane is an unbranched alkane that contains 30 carbon atoms in each molecule. how many hydrogen atoms are present in each molecule of triacontane? 62 32 30 58 60

Explanation:

Step1: Recall alkane formula

The general formula for an un - branched alkane is $C_nH_{2n + 2}$, where $n$ is the number of carbon atoms.

Step2: Substitute $n$ value

Given $n = 30$, then the number of hydrogen atoms $H=2n + 2=2\times30+ 2$.

Step3: Calculate result

$2\times30+2=60 + 2=62$.

Answer:

A. 62
