What functional class(es) does the compound belong to?List only classes for which evidence is given here. Attach no significance to evidence not cited explicitly. Do not over-interpret exact absorption band positions. None of your inferences should depend on small differences like 10 to 20 cm-1.Q1) The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. The only absorption bands this compound exhibits are 2850-3000 (m) and 1450 cm-1 (w).Relative absorption intensity: (s)=strong, (m)=medium, (w)=weak. Q2) The functional groups in an organic compound can frequently be deduced from its infrared absorption spectrum. A compound contains no nitrogen and exhibits absorption bands at 3300 (s) and 2150 (m) cm-1.Relative absorption intensity: (s)=strong, (m)=medium, (w)=weak. The functional class(es) of this compound is(are) a. alkane (List only if no other functional class applies.)b. alkeneh. aminec. terminal alkynei. aldehyde or ketoned. internal alkynej. carboxylic acide. arenek. esterf. alcoholl. nitrileg. ether
