Answer:
Whenever the two groups on each end of a carbon-carbon double bond are the same, two diastereomers are possible.
Explanation:
Double bonds are formed when four electrons are shared between two carbon atoms. The second bond is generally known as a pi-bond while the first bond is called a sigma bond.
The presence of a double bond in a compound leads to restricted rotation about the carbon-carbon double bond. Hence the substituents are 'locked' in a particular configuration.
The more substituted a double bond is, the more stable it is according to Saytzeff's Rule.
Due to steric effects, trans alkenes are generally more thermodynamically stable than cis alkenes since trans alkenes have bulky groups oriented apart from each other.
All these are true statements. The answer selected must be the untrue statement.
Answer:
C + O2 → CO2
Explanation:
C + O2 → CO ----------------- (1)
from equ (1) on reactant side, C has 1 mole, O has 2 moles
from equ (1) on product side, C has 1 mole, O has 1 mole
Thus, to balance the equation, O should have 2 moles
C + O2 → CO2
Answer:
it would be a cation ... i believe
Explanation:
To become a cation, a positively charged ion, an atom would have to lose at least two electrons
It is B: Fixed volume, takes the shape of the container
Answer:
about 0.7 g/mL
Explanation:
Density = mass ÷ volume
D = 5.29 g / (12.6 mL - 5.00 mL)
D = 5.29 g / 7.6 mL
D = 0.696052.... g/mL
D = about 0.7 g/mL
