What type of bond is formed through the unequal sharing of electrons between atoms?
Press to flip
A polar covalent bond.
Provide an example of a molecule with a non-polar covalent bond.
Methane (CH4) has non-polar covalent C-H bonds.
How many lone pairs does oxygen have in the Lewis structure of water?
Oxygen has two lone pairs in the Lewis structure of water.
Describe the difference between a covalent bond and an ionic bond.
Covalent bonds involve the sharing of electrons, while ionic bonds involve the transfer of electrons.
What functional group is characterized by a carbonyl group at the end of a carbon chain?
Aldehydes.
What is the characteristic bonding feature of alkynes?
Alkynes feature at least one carbon-carbon triple bond.
Which functional group is represented by the formula COOH, and provide an example?
Carboxylic acids, an example is pentanoic acid.
What is the typical number of bonds formed by carbon in organic compounds?
Carbon typically forms four bonds.
In methyl fluoride (CH3F), how many lone pairs does the fluorine atom possess?
Fluorine has three lone pairs in methyl fluoride.
How is the formal charge on an atom calculated in a molecule?
Formal charge = Valence electrons - (Bonds + Lone pair electrons).
How are sigma and pi bonds distributed in a triple bond, and which type of bond is stronger?
A triple bond consists of 1 sigma bond and 2 pi bonds. Sigma bonds are stronger than pi bonds.
What primary feature distinguishes alkenes from alkanes in terms of bonds?
Alkenes have at least one double bond, whereas alkanes only have single bonds.
In the structure of an ether, what is the positioning of the oxygen atom?
In an ether, the oxygen is positioned between two carbon atoms.
What is the hybridization of a carbon atom with three bonded groups and no lone pairs?
sp2 hybridization.
What is the bond length relationship between single, double, and triple bonds?
Single bonds are the longest, double bonds are shorter, and triple bonds are the shortest.
Explain what sp3 hybridization indicates in terms of bonded groups around a carbon atom.
sp3 hybridization indicates that the carbon atom is bonded to four groups.
