Answer:

a. H + d. Na

Explanation:

This is Mixture of H and Na. Because of H and in the emission and Absorption spectrum of H Total 5 lines [Red, Green, Blue and Purple (2)) are present and in the spectrum of Na Two yellow lines are present. In the mixture all this lines are are also 5 + Present. Total lines are 5+2= 7 (H+ Na)

Therefore, the answer is a. H + d. Na

Are the statements about hydrogen bonding of the compound below with water true or false? this compound can act as a hydrogen-bo

Lyrx [107]

I searched for complete question (as your question is missing with structure) and found the structure of compound attached below.

Answer:
The compound can neither act as a Hydrogen Bond Donor nor act as a Hydrogen Bond Acceptor.

Explanation:
For two compounds to build Hydrogen Bond Interactions it is compulsory that they must contain Hydrogen atoms which are directly attached to most electronegative atoms like Fluorine, Oxygen and Nitrogen.
As the given compound is 2-Butene (a non polar hydrocarbon), it lacks partial positive Hydrogen (which can act as Hydrogen Bond Donor) and a most electronegative element (F, O or N) which can act as Hydrogen Bond Acceptor. Therefore, this compound will not generate any Hydrogen Bonding with water molecules and will remain immiscible in it.
