The following compound has been found effective in treating pain and inflammation (J. Med. Chem. 2007, 4222). Which sequence correctly ranks each carbonyl group in order of increasing reactivity toward nucleophilic addition?
A) 1 < 2 < 3
B) 2 < 3 < 1
C) 3 < 1 < 2
D) 1 < 3 < 2
<h3><u>Answer: </u></h3>
The rate of nucleophilic attack of carbonyl compounds is 2<3 <1.
Option B
<h3><u>Explanation. </u></h3>
Nucleophilic attack is explained as the attack of an electron rich radical to a carbonyl compound like aldehyde or a ketone. A nucleophile has a high electron density, so it searches for a electropositive atom where it can donate a portion of its electron density and become stable.
A carbonyl compound is a 
hybridized carbon atom with a double bonded oxygen atom in it. The oxygen atom pulls a huge portion of electron density from carbon being very electropositive.
In a ketone, there are two factors that make it less likely to undergo a nucleophilic attack than aldehyde. Firstly, the steric hindrance of two carbon groups being attached with the carbonyl carbon makes it harder for the nucleophile to approach. Secondly, the electron push by the carbon groups attached makes the carbonyl carbon a bit less electropositive than the aldehyde one. So aldehydes are more reactive towards a nucleophilic addition reaction.
Answer:
AsF3:C2CI6
4:3
1.3618 moles: 1.02135 moles(1.3618÷4×3)
C2CI6 is the limting reagent
So the number of moles for AsCI3 is 0.817 moles( number of moles of the limting reagant) ÷3 ×4 (according to ratio by balancing chemical equation)=1.09 moles(3 s.f.)
or
Balanced equation
4AsF3 + 3C2Cl6 → 4AsCl3 + 3C2Cl2F4
Use stoichiometry to calculate the moles of AsCl3 that can be produced by each reactant.
Multiply the moles of each reactant by the mole ratio between it and AsCl3 in the balanced equation, so that the moles of the reactant cancel, leaving moles of AsCl3.

It would be.. sand, slit, clay.
Explanation:
Air bags help lessen injuries in an automobile crash is application of Boyle's law:
Boyle's law states that at constant temperature, the volume of given mass of a gas is directly proportional to the pressure changes.
According to this law, the volume of the air bag will increase. The bag will become bigger as a result of decrease in the gas pressure in the bag.
The bag was packed with gases under high pressure and their volume decreases appreciably. After a collision, pressure reduces and the gas expands.
helium balloon decreases in size when you put it into a freezer
A can of spray paint will explode if tossed into a fire
Both are application of Charles's law:
According to this law "the volume of a fixed mass of a gas varies directly as its absolute temperature if the pressure is constant".
The helium balloon decreases in size because the temperature is lowered. The particles will keep tending towards a state of rest.
A can spray paint explodes because the gas in it will keep expanding as the temperature increases in a fire.
