BIOL 240 QUIZ 1 QUESTIONS & ANSWERSQuestion 1 (4 points) What is the reason why there are so many organic compounds? Question 1 options:
Unlike inorganic compounds, organic compounds can be cyclic.
Organic compounds can be larger than inorganic compounds.
Organic compounds are produced by living things.
Carbon atoms can form stable covalent bonds with other carbon atoms.
It is true that organic compounds are produced by living things and they can be larger than inorganic compounds. However, the best answer is the carbon atoms that can form stable covalent bonds with other carbon atoms. Organic compounds always have carbon atoms which inorganic compounds usually lack. This gives the
organic compounds the massive opportunity to be found almost everywhere, since carbon atom can form extensive bonds with other atoms or molecules.
Question 2 (4 points) Which statement below is correct? Question 2 options:
Functional groups are the parts of molecules used to organize organic compounds into different classes.
All of the answer choices listed here are correct statements about functional groups.
Functional groups are to organic chemistry as polyatomic ions are to inorganic chemistry.
Functional groups can be chemically bound to each other in order to develop larger molecules.
In organic chemistry, functional groups are groupings of atoms that contribute to the molecule's chemical properties and engage in predictable reactions.
They are also the portions of molecules that are used to classify organic compounds based on their characteristics, reactivity, and interactions with other molecules.
Question 3 (4 points) What is meant by the term "saturated" when describing hydrocarbons? Question 3 options:
The hydrocarbons are saturated with carbons in the skeleton of the compounds. The container holding the compound has no other compound.
They are saturated with water.
They are saturated with hydrogen and only have single bonds between carbons.
Question 4 (4 points) Identify the correct statement: The alkanes represent one family of organic compounds _____.
Question 4 options: in which the halogens are a major
component. that is composed of carbon and hydrogen. in
which there is at least one double bond between carbons. in
which hydrogens can be bonded to other hydrogens.
Question 5 (4 points) Identify the correct statement. Cycloalkanes are _____. Question 5 options:
None of the statements listed here as choices are correct. compounds that have a flat molecular structure. saturated hydrocarbons. compounds that cannot have the hydrogens removed and replaced by chlorine. The correct statement will be Cycloalkanes are Saturated hydrocarbons . A compound having a long chain of carbon with hydrogen is termed hydrocarbon. And cycloalkanes are hydrocarbons that have the formula of CnH2n and are the type of hydrocarbon
that contain a ring of single bonded-carbon atoms. And the most important point of these cycloalkanes is that they are cyclic in nature (or can say that they are not flat molecular structures, they are ring structures). The general formula for the hydrocarbons is CnH( 2n + 2) but cycloalkanes have the formula CnH 2n because they have two fewer hydrogen atoms because two hydrogens were removed out and two carbon-carbon joined to form a ring for the cycloalkanes. As they have only single bonds between the carbon atoms so, they are saturated. (and unsaturated compounds have double or
triple bonds). Question 6 (4 points) Which of the following formulas represents a saturated hydrocarbon? Question 6 options:
C2H4
C2H6
