Question

Chemists use a shorthand notation to be more efficient when drawing larger molecules that contain carbon. The carbon atoms are replaced by corners and the end of lines. Hydrogen atoms are omitted from most carbon atoms. The three shorthand drawings below represent the same three molecules from number 1 above. Use this information to redraw the full structures showing all of the carbon and hydrogen atoms. Redraw the molecule below but show all of the carbon and hydrogen atoms. Once you have completed your drawing provide the chemical formula for this molecule.

Explanation / Answer

Chemical formula gives us the information of number of atoms of each element in a molecule/compound. Table gives the info about empirical, chemical or molecular, and condensed formula of these compounds. Drawings shown in the question is actually structural formula.

Compound Name empirical formula Chemical/molecular formula Condensed formula a n-butane C2H5 C4H10 CH3CH2CH2CH3 b Acetaldehyde/Ethanal C2H4O C2H4O CH3CHO C Ethylamine C2H7N C2H7N CH3CH2NH2
