Fall 01: Quiz 2. Ch 4-6 20points Name If you do not want your graded quiz placed in the box outside my office, then please tick here (1 and 3-10) are True or False. 1) The mirror image of an achiral molecule is invisible. 2) Name an everyday object which is chiral (and not a part of your body or an item of clothing). 3) Bulky anions are bad nucleophiles because their bulk creates steric hindrance. 4)A favorable entropy change results from in increase in disorder. 5)The lower the bond dissociation energy of a bond, the easier it is to break. 6)This molecule is achiral. CO2CH3CH3H3CClClCO2CH37)Polarizable anions make better nucleophiles than anions that are less polarizable. 8)These compounds are enantiomers. OHHCF3CH3CF3HHOCH39) SN1 reactions always proceed with retention of stereochemistry. 10)A nucleophilic substitution is a reaction where a nucleophilic species replaces another group or atom in a molecule.
