Assessment: The Chemistry of Carbon

Which of the following statement is CORRECT?

• Chemistry can be divided into organic

  chemistry and inorganic chemistry.

• There are two forms of compounds namely aliphatic and aromatic hydrocarbons

• Hydrocarbons can only form single bonds.

• Properties of metals such as calcium is one of the focus of organic chemistry.

How will you describe an alkane?

• An alkane is a hydrocarbon with single bond.

• An alkane is a hydrocarbon with double bond

• An alkane is a hydrocarbon with triple bond.

• An alkane is a hydrocarbon without bond.

Which of the following statements is NOT true?

• The single bond that connects carbon atoms to carbon atoms is quite strong, so the subsequent long chains and ring structures are not fragile.

• The carbon-carbon covalent bonding pattern does not satisfy the Octet rule.

• Because carbon has four valence electrons and needs eight to satisfy the Octet rule, it can bond with up to four additional atoms, creating countless compound possibilities.

• none of the above

Answer explanation

Carbon has 4 valence electron. Carbon-Carbon bond achieve stbility or Octet Rule.

Which of the following is NOT an organic compound?

• NaCl

• C6H10O5

• CH4

• CH3CH2CH3

Answer explanation

NaCl do not contain Carbon-Hydrogen bond.

What type of hydrocarbon has a double bond?

• alkane

• alkene

• alkyne

• none

Which of the following is NOT an organic compound?

• CaBr2

• CH4

• C6H12O6

• CH3OH

Answer explanation

CaBr2 do not contain Carbon-Hydrogen bond.

It is the study of the compounds that do not contain carbon.

• Inorganic chemistry

• Organic chemistry

• Analytical chemistry

• Biochemistry

Answer explanation

Inorganic chemistry is the study of compounds not covered by organic chemistry. It is the study of inorganic compounds, or compounds that don't contain a C-H bond.

Which of the following statements is true about carbon?

• Carbon has six valence electrons.

• Carbon transfers electrons with other atoms.

• Carbon is capable of forming double bonds and triple bonds

Answer explanation

carbon atom can bond with another carbon atom two or three times to make double and triple covalent bonds between two carbon atoms

How will you describe an alkene?

• An alkene is a hydrocarbon with single bond.

• An alkene is a hydrocarbon with double bond

• An alkene is a hydrocarbon with triple bond.

• An alkene is a hydrocarbon without bond

It is a type of hydrocarbon which is composed of chains of carbon atoms.

• aliphatic hydrocarbon

• aromatic hydrocarbon

• alkanes

• alkynes

Answer explanation

Aliphatic Hydrocarbon is Hydrocarbons based on chains of C atoms
