Explain why nonfluoro-2-methyl-2-propoxide is a much weaker base than tertbutoxide.
* Incorrect. Explain why phenoxide is a much poorer nucleophile and weaker base than cyclohexoxide: Do Our -0. Nat -0. Nat Sodium phenoxide Sodium cyclohexoxide O The negative charge on phenoxide is stabilized by resonance and delocalized over multiple atoms. O The electron pairs in phenoxide are less available for nucleophilic reactions relative to cyclohexoxide because the electrons are delocalized due to resonance. O The electron pairs in cyclohexoxide are less available for nucleophilic reactions relative to phenoxide because the...
Is sodium acetate a stronger or weaker base than sodium hydroxide (NaOH). Explain.
6) Applying resonance. Amides such as acetamide (CH3CONH2) are much weaker bases than amines, such as ethylamine (CH3CH2NH2). Explain why (try resonance). Predict also how protonation (reaction with H+ ) of both species would go (again, resonance can help).
Alcohols are weaker acids than carboxylic acids because: the anion in the conjugate base of the alcohol is delocalised the anion in the conjugate base of the alcohol is localised the O-H group in the alcohol will undergo hydrogen bonding the O-H group in the alcohol will not undergo hydrogen bonding
Explain why 3-methylcyclohexene is more stable than
methylcyclohexane.
ОН HA -H20 2-Methylcyclohexanol cis, and trans) 3-Methyl- 1-Methyl Methylene- cyclohexene cyclohexene cyclohexane
- Which is the weaker base: nitrogen trifluoride or ammonia? Explain your choic - Name three polar, aprotic solvents and three polar, protic solvents.
4. This equilibrium reaction of bromo-pyridines with BuLi favours formation of the weaker base which can be treated with a suitable electrophile. Explain why only the 4-substituted pyridine is obtained in these reactions. Ac Br i) BuLi i) BuLi ii) Ac20 i) Ac20 Br

why are anti-stokes lines generally weaker than stokes lines in vibrational raman spectra?
1) Brief answers a) Explain why FeS is much less solute in water than Fe(OH)2 and Fe(OH)2 is much more soluble than Fe(OH)3 b)will Cr3+react more strongly with Cl-or PR3. Why? 2) Brief answers a) Would you expect lead (Pb2+ soft to be found oxide in nature? b) Explain the following observation interns pf the HSAB theory: OH- + CH3HgS --> CH3HgOH +S2- Equilibrium displaced to the left.
are grain boundaries stronger or weaker than slip system? Explain What causes compressive forces in a crystalline lattice?
