Substitution Reactions are those reactions in which one nucleophile replaces another nucleophile present on a substrate. These reactions can take place via two different mechanism i.e SN¹ or SN². In SN¹ substitution reactions the leaving group leaves first forming a carbocation and nucleophile attacks carbocation in the second step. While in SN² reactions the addition of Nucleophile and leaving of leaving group take place simultaneously.
Example:
OH⁻ + CH₃-Br → CH₃-OH + Br⁻
In above reaction,
OH⁻ = Incoming Nucleophile
CH₃-Br = Substrate
CH₃-OH = Product
Br⁻ = Leaving group
Organic reactions are typically slower than ionic reactions because in organic compounds the covalent bonds are first broken, this breaking of bonds is a slower step, while, in ionic compounds no bond breakage is required as it consists of ions, so only bond formation takes place which is a quicker and fast step.
Answer:
B.Number of times a person can squeeze a clothespin
Explanation:
Hello,
Since the idea is to detect the effect of the previous exercise on the number of times a person can squeeze a clothespin and this is done by setting a specific time of 1 minute (a controlled variable) and subsequently record the times, one can state that the times the clothespin is squeezed depend both on the type of exercise and the time, thus those times turn out into the dependent variable.
Best regards.
Answer:
Explanation: first use a balance to get the masses of these items. Once the masses of these items are measured, we can then calculate the moles.
The mole is = mass/molarmass
