Which compound is more acidic?
(L or R) - ANSWER: R (The electronegative Cl pulls negative charge away from O...making the negative
charge more stable...allowing an H+ to leave more easily...more acidic)
Which hydrogen is more acidic?
(L or R) - ANSWER: L (with inductive effects electronegativity wins...however, ClH is a stronger acid
than FH...there, atom size stabilizes the charge)
(L or R) - ANSWER: R (HO⁻ is more stable than CH3O⁻)
Which H is most acidic?
(Pick in head then check answer) - ANSWER: The H on Carbon 4 is the most acidic
Which hydrogen is more acidic?
(L or R) - ANSWER: R (normally, the atom's electronegativity takes precedence over orbital, but this (N
vs. ≡) is the exception)
What is the hybridization of N?
(sp, sp2, or sp3) - ANSWER: sp3 (lone pair is in hybridized tetrahedral orbital)
What is the hybridization of N?
(sp, sp2, or sp3) - ANSWER: sp2 (lone pair is participating in resonance)
What is the hybridization of O?
(sp, sp2, or sp3) - ANSWER: sp2 (lone pair is participating in resonance)
What is the hybridization of O?
(sp, sp2, or sp3) - ANSWER: sp3 (lone pairs are in hybridized tetrahedral orbitals)
Functional Group ? ______
Suffix ? ______ - ANSWER: ester oate
Functional Group ? ______
Suffix ? ______ - ANSWER: Amine amine
- ANSWER: al
- ANSWER: one
name compound (include stereoisomerism: Z/E, R/S) - ANSWER: E hex-3-en-1,5-diyne (en comes
before yn)
name compound - ANSWER: but-1-en-3-yne (en comes before yn)
- ANSWER: hex
4, 5, or 6? - ANSWER: 4
______ substituents - ANSWER: axial
______ substituents - ANSWER: equatorial
