Answer:

2-chloro-1-methyl-cyclohex-1,4-diene.

Explanation:

Hello,

In this case, the addition of hydrochloric acid acts as an electrophilic atack in which the hydrogen bonded to the double-bonded carbon connected to the carbon with the methyl substitution is substituted by the chlorine from the hydrochloric acid, in such a way, 2-chloro-1-methyl-cyclohex-1,4-diene is produced as one equivalent of HCl is used therefore one substitution will be attained for chlorine, and hydrogen as a side product as shown on the attached picture.

Best regards.

A student explained to the class that helium has 8 valence electrons because it is in group 18. Is the student correct?
lys-0071 [83]
<span>The student is incorrect because helium has 2 valence electrons and it's in group 18 because the first energy level is full. Although helium is placed in Group 18 which generally has 8 valence electrons, it does not have 8 valence electrons as the student suggested. It was grouped together with the noble gases because it exhibits similar properties with them. </span>

Which statement correctly explains how magnesium and chlorine combine to form magnesium chloride?
AysviL [449]
You did not include the statements but since magnesium chloride is ionic substance that we know that magnesium and chlorine formed an ionic bond.  Therefore your statement most likely will talk about how one magnesium atom gave up 2 electrons while two chlorine atoms took 1 electron.  The reaction looks like Mg+2Cl⇒MgCl₂.  
I hope this helps.  Let me know in the comments if anything is unclear.
