CHEM134 C001 SPRING 2024 DIGITAL ACID
BASE CHEMISTRY COMPLETE TEST PAPER
WITH ANSWERS
◉ carboxylic acid.
Answer: -OH group bonded to C and O double bond
gives up a proton-deprotonated group called carboxylate
◉ amines.
Answer: carbons bonded to nitrogen
can accept protons at lone pairs
◉ constitutional/structural isomers/stereoisomers.
Answer: same empirical formula, different structure
◉ optical isomers/enantiomers.
Answer: isomers that are mirror images of each other, which differ
in how they react to polarized light
, ◉ geometric/cis-trans isomers.
Answer: stereoisomers with different rotations about a double bond
cis isomers have like groups on the same side, trans isomers have
like groups on opposite sides
◉ alkyl group.
Answer: structure that remains after removing an H atom from an
alkane
◉ IUPAC System.
Answer: Locant-Prefix-Parent-Suffix
◉ Increasing molecular weight....
Answer: increases boiling point and melting point, and decreases
dispersion forces
◉ Increasing molecular size.....
Answer: increases dispersion forces
◉ What makes a molecule chiral?.
Answer: It has a plane (NOT LINE) of symmetry
