Answer Sheet:
Nucleophile is defined as the species containing negatively charge or having lone pair of electrons.
The nucleophile are attack to the electrophilic substrate. The nucleophilicity depends on the the charge density and size of the nucleophile.
Larger size or bulkier nucleophile are more difficult to attack the substrate due to staric hindrances. Thats why the bulkier nucleophiles are poor nucleophiles.
So the correct option is- B. poor
Add Answer to:
The bulkier the molecule the more steric hindrance. Does steric hindrance make a good or poor...

Acetylation of ferrocene and column chromatography
Lab 4: Question 3 Homework • Unanswered Important ... The solvent is changed from petroleum ether to diethyl ether after the ferrocene is collected from the column. Why not use diethyl ether the entire time? Because diethyl ether is more polar than petroleum ether Because petroleum ether selectively elutes ferrocene since it contains more ether oxygens than diethyl ether Because diethyl ether would lead to a poorer separation of ferrocene and acetylferrocene Both a...

Why are nucleotides a good molecule to make DNA out of, while amino acids are good for making proteins? A good answer will include: -how nucleotides compare to amino acids in terms of diversity of shape and feel -how the structure and funciton of DNA compares to the structure and function of proteins -what is the 'job' of DNA? why are the nucleotides good for allowing DNA to carry out its functions? what is the job of a protein? how...

1. A small company must decide whether to merge with a larger company to make more investments. If they merge and it is a good sales year, there will be a $840,000 profit; if they merge and it is a poor sales year, there will be a deficit of $ 260,000. If they do not merge and it is a good sales year there will be a $480,000 profit; if they do not merge and it is a poor sales...
