CH₃CH₃ + Cl₂ → CH₃CH₂Cl + HCl

  • This reaction take place in the presence of light/UV rays. (i.e, photochemical reaction)
  • It's a Chlorination reaction because here there's addition of chlorine.
  • It's a substitution reaction because Cl substituted H from place and attach there.

Option which is NOT correct is

In your own words list the rules for naming hydrocarbons and substituted hydrocarbons. Be detailed in listing all rules includin
Irina18 [472]

Answer :

The basic rules for naming of hydrocarbons are :

First select the longest possible carbon chain.

The longest possible carbon chain should include the carbons of double or triple bonds.

The naming of alkane is done by adding the suffix -ane, alkene by adding the suffix -ene, alkyne by adding the suffix -yne.

The numbering is done in such a way that first carbon of double or triple bond gets the lowest number.

The carbon atoms of the double or triple bond get the preference over the other substituents present in the parent chain.

If two or more similar alkyl groups are present in a compound, the prefixes di-, tri-, tetra- and so on are used to specify the number of times of the alkyl groups in the chain.

Nh4i(aq)+koh(aq)→ express your answer as a chemical equation. identify all of the phases in your answer.
tester [92]
NH4I (aq)  +  KOH  (aq)  in   chemical   equation  gives

   NH4I (aq)  +  KOH (aq)   =  KI  (aq)  +  H2O(l)  +  NH3  (l)

Ki  is  in  aqueous  state  H2o   is  in   liquid  state  while  NH3  is  in  liquid  state

from  the  equation  above  1 mole of  NH4I (aq) react  with  1 mole of KOH(aq) to  form  1mole of KI(aq) ,  1mole of H2O(l)  and 1  Mole  of NH3(l)
