Question

Second Academic Assignment Student's Name: 1. Identify formulas of organic compounds. KCI _CaH10 _H2SO4 CaCl2 C3H7C1 2. Identify the properties more typical of an organic compound. Lis soluble in water _has a low boiling point contains carbon and hydrogen contains ionic bonds contains Li and F _contains covalent bonds produces ions in water 3. Draw the condensed, expanded, and skeletal formulas for the following alkanes. a. methane b.ethane c. pentane d.cyclopropane

Answer 1

KCl, H2SO4 ,CaCl2 are inorganic compounds

Therefore organic compounds are: C4H10,C3H7Cl
*********************************
2) organic compounds formed by covalent bonds.Most
of them are volatile ,thus have low boiling point.
They are usually non polar in nature ,so insoluble in
polar solvent water.
Thus organic compounds have following properties

- Has low boiling point
-contains carbon and hydrogen
-contains covalent bonds
****************
In expanded form all atoms and bonds will be shown

In condensed form ,bonds will not be visible,only atoms
will be shown

In skeletal form ,only bonds will be shown .It will not
show carbon and hydrogen atoms.
