What are the elements so i can help?????
Hello!
From this list, a) HCl is not a weak acid.
Hydrochloric Acid, or HCl, is one of the most common examples of a strong acid. Strong acids dissociate completely in water to generate H⁺ and A⁻ ions. For HCl this reaction is as follows:
HCl → H⁺ + Cl⁻
Being more precise, for an acid to be called strong it needs to be stronger than hydronium ion (H₃O⁺) <span>pKa</span> <span>< -</span>1.74.
Have a nice day!
Answer:
D.
Explanation:
CH₃C≡ CCH₂CH₂Cl
Since there are 5 carbons so the suffix used is "pent"
There is a triple bond so its alkyne
So the compound becomes 2-pentyne (2 because the triple bond is with the 2nd carbon)
Then,
The functional group of chlorine is attached with 5th carbon So the compound becomes
5-chloro,2-pentyne
