Question

Rank the following substances in decreasing order of heat of combustion -most exothermic rightarrow least exothermic-A - B - CC - B - AC - A - BB - A - C

Toppr Admin · Accepted Answer

More is the number of carbon atoms in alkane more is its heat of combustion-

Rank the following substances in decreasing order of heat of combustion (most exothermic → least exothermic)A>B>CC>B>AC>A>BB>A>C

More is the number of carbon atoms in alkane more is its heat of combustion.

Rank the following substances in decreasing order of heat of combustion (most exothermic $\to$ least exothermic)

$A > B > C$
$C > B > A$
$C > A > B$
$B > A > C$
