can have two or more covalenely bonded atoms, Hence, the polarity or nonpolarity of a molecule depends on the net effect of all its bonds
(a)
the polar or nonpolar nature of the bond is the same as the nacure of the molecule
(a)
Compounds that result from covalent bonding are called
(a)
are generally soft because the atoms are attracted by relatively weak covalent bonds. Unlike jonic compounds, aqueous covalent compounds, such as sugar solution,do not conduct electricity because they have no mobile charged particles, That is, molecules have zero net charge when dissolved in water.
(a)
have lower melting and boiling points.
(a)
To melt or boil these substances, only the forces of attraction between the molecules, not the covalent bonds within the molecules, need to be broken..
(a)
unique element that can form various compounds.
(a)
are those that mainly contain carbon and hydrogen and sometimes small quantities of other elements such as nitrogen, sulfur, and phosphorus
(a)
include carbohydrates, fats, and proteins
(a)
. It can also form bonds with other types of nonmetal atoms, to produce compounds with chain, branched, or ring structures
(a)
These bonds result when the valence orbitals of carbon undergo a process called
(a)
As the number of carbon atoms in a chemical formula decreases, more compounds can be formed because of the various types of covalent bonding that can arise and the many possible arrangements that can occur among the carbon atoms
true
false
present in millions of organic and inorganic compounds
(a)
composed of carbon and hydrogen atoms only
(a)
They make
up the simplest class of organic compounds and can be further classified based on their structure and
the type of covalent bond they contain
(a)
are hydrocarbons that contain single covalent bonds only: there are no double or triple bonds in the molecules
(a)
have the general formula Csub0 Hsub26+21 where ln 21 the number of carbon atoms in the molecule/ They are generally used as fuels and solvents
(a)
are unsaturated hydrocarbons that contain at least one triple covalent bond between two carbon atoms./They have che general formula Csub n ,Hsub2n-2
(a)
An example of alkyne is'
(a)
An example of alkyne is'
(a)
/arealkanes in which the carbon atoms are arranged in a ring. Those that contain only
one ring have the general formula Csub n ,Hsub 2n
(a)
The structural formulas of (a) - are usually represented
as polygons; each corner corresponds to a carbon atom
is used as a solvent in
paints and varnishes
(a)
was formerly used as an anesthetic
(a)
