Which carbonyl compounds do not undergo an aldol reaction when treated with −oh in h2o? select all that apply?
1 answer:
Answers:
Among many few compounds are shown below which can not undergo Aldol Condensation reactions.
Explanation:
Aldol Condensation reactions are given by those carbonyl compounds which are capable of forming conjugate bases called as Enolates. Enolates are formed when carbonyl compounds having hydrogen atoms at alpha position are treated with strong bases. This hydrogen atom at alpha position is mildly acidic in nature and readily donated to base as the upcoming conjugate base i.e. has stability due to resonance.
So those carbonyl compounds which lacks these acidic protons at alpha position are not able to form enolates, Hence, unable to undergo Aldol Condensation reactions. Few examples are attached below,

Answer: 250 ml of stock solution with molarity of 12.0 M is measured using a pipette and 250 ml of water is added to volumetric flask of 500 ml to make the final volume of 500 ml.
Explanation:
According to the dilution law,
where,
= concentration of stock solution = 12.0 M
= volume of stock solution = ?
= concentration of diluted solution= 6.00 M
= volume of diluted acid solution = 500 ml
Putting in the values we get:
Thus 250 ml of stock solution with molarity of 12.0 M is measured using a pipette and 250 ml of water is added to volumetric flask of 500 ml to make the final volume of 500 ml.
132.67 K is the temperature at which 55 grams of chlorine gas exert a pressure of 245 kPa at a volume of 3.4 liter.
Explanation:
Data given:
mass of chlorine gas = 55 grams
atomic mass of chlorine gas = 71 grams/mole
pressure of chlorine gas = 245 kPa 0R 2.41 atm
volume of the chlorine gas = 3.4 litres
temperature of the chlorine gas = ?
R = 0.08201 Latm/moles K
n =?
Assuming that chlorine behaved like ideal gas, the formula used will be,
PV = nRT
number of moles =
number of moles=
number of moles = 0.77
putting the values in ideal gas equation:
T =
T = 132.67 K
temperature is 132.67 K
Explanation:
these are the scientific method.
