Dear friends may I know an appropriate route of synthesis of 2-amino-5-methoxy benzenesulfonic acid?

1.0gm of a sample of an organic compound was burnt in excess of oxygen to yeld 3.03gm of co2 and 1.55gm of h2o if the molecular mass of the compound is 58 , find it's molecular formulaC4H10

mass of acetic acid?
molar mass=60.052 g/mol
heat capacity=8.43kj/C
temp increase from 24.5 C to 36.8 C
deltarU for combustion =-874.2kj/mol

In the reaction c4h10 + o2= co2 + h2o 172.5 g of c4h10 reacts with excess o2. How many grams of co2 will be produced?

In the reaction c4h10 + o2= co2 + h2o 172.5 g of c4h10 reacts with excess o2. How many grams of co2 will be produced?

2-bromobutane and 1 bromobutane are example of what type of isomerism?

How many alpha-hydorgens are required for a Claisen condensation to be successful and why?

Which of the following statements is true?

select one:
1) The rate of SN1 reactions depends only upon the nature of the nucleophile
2) The carbocationic intermediate in SN1 reactions has no effect on the rate of reaction.
3) All SN1 reactions have the same rate.
4) The rate of SN1 reactions is independent of the nature and concentration of the nucleophile
5) The rate of SN1 reactions depend on the nature of both the nucleophile and the electrophile.

Rank these species in order of increasing nucleophilicity:

A Si-H sigma bond

B Oxygen lone pair

C Carbon-Oxygen double bond
