Draw the structure of the aromatic compound para-aminochlorobenzene (para-chloroaniline). Draw the molecule on the canvas by cho
weqwewe [10]

Answer:

Explanation:

In the picture you have the answer.

Now, let's analize the structure, so you can know why the structure in the picture is the correct structure.

The aniline is the name that receives the benzene with a NH2 group as one of it's substituent. Now, This group is a really strong activating group and in the nomenclature priority, it has more order priority than any halide.

Now, it says that the chloro it's on the para position. The "para" position in a aromatic ring, in this case, the benzene, refers to the position of this substituent to the first substitued position. In this case, the NH2 it's on the position 1 or carbon 1, the para position, means that it's on position 4 of the ring. The ortho position is carbon 2, and meta position is carbon 3 of the benzene. So, according to this, the p-chloroaniline it's on picture attached.

Answer:

  • Because<em> alkenes and alkynes</em> are defined as molecules with at least one double (in the case of alkenes) or triple (in the case of alkynes) bond between two carbon atoms, while alkanes have only single bonds between any pair of carbon atoms.

Explanation:

<em>Alkenes</em> and <em>alkynes</em> are unsaturated molecules, because they have, at least, two adjacent carbon atoms bonded together by either a doubler or a triple bond: - C = C -  or - C ≡ C -.

Hence, at least two carbon atoms are needed to form those double or triple bonds, while alkanes have only single bonds. The example of alkane with only one carbon atom is methane: CH₄, which is the most simple alkane.

The most simple alkene is CH₂ = CH₂, and the most simple alkyne is CH≡CH.

As you see, the very definition of alkenes and alkynes forces that those molecules must have at least two carbon atoms.
