Question

fill in the systematic names of the following chemical compounds. note: for compounds containing hydrogen, you may give the common name instead. your answer

molecular formula	name of compound
bp
$cs_2$	carbon disulfide
$bi_3$	boron triiodide
$nh_3$	ammonia

Explanation:

Step1: Name binary compounds

For binary covalent compounds, we use prefixes to indicate the number of atoms of each element. The first - element in the formula is named as the element itself, and the second - element is named with the suffix - ide.

Step2: Determine prefixes for BP

There is 1 boron (B) and 1 phosphorus (P). The prefix for 1 is mono - (but we usually omit the mono - for the first element). So the name is boron phosphide.

Answer:

molecular formula	name of compound
$BP$	boron phosphide
$CS_2$	carbon disulfide
$BI_3$	boron triiodide
$NH_3$	ammonia
