define molecular compound in easy language
Answers
Binary molecular compounds are composed of only two elements. ...Molecular compounds are more difficult to name because the atoms combine through covalent and not ionic bonds. Therefore we cannot use the electrical neutrality rule for thesecompounds. Most molecular compounds are made from nonmetals.

A molecular compound is a compound formed by two or more non-metals, as opposed to an ionic compound which which is composed of a metal and a nonmetal.
Look at a preriodic table and if the compound you are looking at it made up entirely of elements from the right side of the table then it's a molecule.
Examples include carbon dioxide, methane, and sugar.
WRITING FORMULAS FOR COVALENT COMPOUNDS
Certain rules apply to the way names of covalent compounds are written:
The more electropositive element (further left on the periodic table) is listed before the more electronegative element (further right on the periodic table).
The second element is given an -ide ending.
Prefixes are used to denote how many atoms of each element are present in the compound.
PREFIXES AND MOLECULAR COMPOUND NAMES
Nonmetals may combine in a variety of ratios, so it is important that the name of a molecular compound indicates how many atoms of each type of element are present in the compound. This is accomplished using prefixes. If there is only one atom of the first element, no prefix is used.
It is customary to prefix the name of one atom of the second element with mono-. For example, CO is named carbon monoxide rather than carbon oxide.” R
