Is CH3COONa a strong nucleophile?
In d) CH3COONa is weak base and weak nucleophile.
Is OCH3 strong or weak base?
An alkoxide molecule has more steric hindrance and less distinct polarization, making it less attracted to the positive carbon center. So OCH3− is a weaker nucleophile than the hydroxide ion in a protic solvent though OCH3− is a stronger base.
Is ch3ch2oh a strong base?
For example, RO- like HO- (hydroxide) CH3O-, CH3CH2O-, ect. are both strong bases and strong nucleophiles.
What is a hindered base?
As the name suggests, a non-nucleophilic base is a sterically hindered organic base that is a poor nucleophile. Typical non-nucleophilic bases are bulky, such that protons can attach to the basic center but alkylation and complexation is inhibited.
Why is NaOCH3 a strong base?
Why is NaOCH3 a strong nuc and strong base? These are strong nucleophiles because it’s attached to a metallic group Na+ so it’s automatically a negative anion.
Is ch3 3co a nucleophile?
Answer: Since NaOCH3 is a strong nucleophile and base, it will force a 2nd-order mechanism. It is not a bulky base, so the 2° alkyl halide will give a mixture of E2 and SN2 products.
Is methoxide a strong base?
Methoxide (methoxide ion; MeO-): CH3O-; the conjugate base of methanol. A strong base (frequently used in E2 and enolate reactions) and a good nucleophile.
Why is CH3OH stronger than CH3CH2OH?
(c) Both CH3OH and CH3CH2OH can H-bond but CH3CH2OH has more CH bonds for greater dispersion force interactions. Therefore, CH3CH2OH has the higher boiling point.
Why is CH3CH2O a strong Nucleophile?
In our first option(CH3CO2-), resonance is occurring between the two oxygen atoms, decreasing the electron density on oxygen atom. Nothing like this occurs in our second option(CH3CH2O-) which means it has more electron density than the first compound, hence second compound is more nucleophilic.
Is Et3N a strong base?
Triethylamine is a stronger base than Pyridine and the ionic form is stablized. Therefore nucleus of Nitrogen atom has stonger attraction for electrons in pyridine that means it is less available for coordination with a protons compared to Et3N electron pair. Thus pyridine is a weak base.
