Specify the functional groups by letters (A to G) as given in the list below. Use only one letter per box. If there are fewer th
Oksanka [162]

Answer:

(b) amino group

e) carboxyl group

Explanation:

The functional group in an organic compound distinguishes it from other compounds. It is usually the site where chemical reactions takes place.

       CH₃-HC(NH₂)-COOH

There are two functional groups in this organic compoud:

  • The NH₂ group is called the amino group
  • The COOH is a carboxyl group

Draw the lewis structure for butanal, which has the condensed formula ch3(ch2)2cho. show all hydrogen atoms and lone pairs of el
sergejj [24]

There are 10 hydrogen atoms that bind and there are 2 pairs of free electrons in the non-binding O atom

<h3>Further explanation</h3>

Aldehydes are alkane-derived compounds containing carbonyl groups (-CO-) where one bond binds to an alkyl group while another binds to a hydrogen atom.

The general structure is R-CHO with the molecular formula :

\large{\boxed{\boxed{\bold{C_nH_{2n}O}}}

Naming is generally the same as the alkane by replacing the suffix with -al

Butanal or butyraldehyde is an aldehyde which has 4 C atoms

Inside the structure there are 3 atoms involved in bonding:

  • 1. Atom C with 4 valence electrons, requires 4 electrons to reach the octet
  • 2. Atom O with 6 valence electrons, requires 2 electrons to reach the octet
  • 3. Atom H with 1 valence electron, requires 1 electron to reach a duplet

In describing Lewis's structure the steps that can be taken are:

  •  1. Count the number of valence electrons from atoms in a molecule
  • 2. Give each bond a pair of electrons
  • 3. The remaining electrons are given to the atomic terminal so that an octet is reached
  • 4. The remaining electrons that still exist in the central atom
  • 5. If the central atom is not yet octet, free electrons are drawn to the central atom to form double bonds

In the Butanal structure (C₄H₈O) there is 1 double bond of the functional group (-CHO) between the C atom and the O atom
