Answer:
the answer to this is 74 :)
Answer:
False.
Explanation:
The given statement is false because for hot vacuum filtration, the filter paper should be wet rather than dry when pouring the hot solution into the Buchner funnel. This is because The possible explanation the filter paper needs to be wetted is not only to allow it to adhere to the funnel, but also to promote the solute to filter down readily across its pores of the paper without wetting it (this is true for organic and aqueous solvents).
If I'm not mistaking the answer is C. Reactiviy with oxygen. Hopfully I'm correct and I hope it helps!
Answer:
373.15 K
Explanation:
Given data:
Temperature in degree Celsius = 100°C
Temperature in kelvin scale = ?
Solution:
To convert the degree Celsius into kelvin scale we add the given degree Celsius into 273.15.
100°C +273.15 = 373.15 K
Answer:
SN2
Explanation:
The first step of ether cleavage is the protonation of the ether since ROH is a better leaving group than RO-.
The second step of the reaction may proceed by either SN1 or SN2 mechanism depending on the structure of the ether. Methyl and primary ethers react with HI by SN2 mechanism while tertiary ethers react with HI by SN1 mechanism. Secondary ethers react with HI by a mixture of both mechanisms.
Dipentyl ether is a primary ether hence when treated with HI, the reaction with HI proceeds by SN2 mechanism as explained above.
