25 Questions
How many covalent bonds can a carbon atom form with four hydrogen atoms?
One
Why does a carbon atom always form four covalent bonds?
It has four valence electrons
If a carbon atom forms five covalent bonds, what does this indicate?
It is incorrect as carbon can only form four covalent bonds
What happens if a carbon atom forms three covalent bonds?
It still needs to form one more bond to complete its valence shell
If a carbon atom forms only two covalent bonds, what effect does this have on its reactivity?
It makes it more reactive
What is one reason that carbon can form many different compounds?
Its ability to form stable carbon-carbon bonds
In a carbon-hydrogen or a carbon-carbon bond, where is the electron pair shared?
Almost equally by the nuclei of the atoms forming the bond
Which type of bond involves nuclei sharing the electron pair almost equally?
Carbon-hydrogen bond
What type of bond does ethane contain?
Carbon-carbon bond
According to the general rule “like dissolves like,” what type of compounds will not form a solution?
Nonpolar and polar compounds
Why is it mentioned that carbon can form many different compounds?
Due to its capability to make various types of bonds
Which type of compounds is mentioned as an example that will not form a solution?
Ionic compounds
What is the guiding principle behind the statement 'like dissolves like'?
Similar substances have similar solubilities
Why do nonpolar compounds and polar compounds not form a solution according to the general rule?
Because they have different polarities
Which type of compounds exhibit a stronger tendency to form solutions based on the 'like dissolves like' concept?
Ionic and polar compounds
What is the recommended approach for numbering carbon atoms in a parent carbon chain?
Start from the end closest to the first carbon atom with an alkyl or other group
Why is it important to number carbon atoms in a parent carbon chain?
It affects the IUPAC naming of organic compounds
If a compound has multiple alkyl groups, how should carbon atoms be numbered?
Start numbering from the end closest to any alkyl group
In which situation would it be acceptable to randomly assign numbers to carbon atoms in a chain?
When there are no alkyl groups present
What would be the consequence of starting numbering from the end farthest from any functional group?
It would lead to incorrect IUPAC naming
What is the name of the parent alkane in the provided text?
Pentane
How many carbon atoms are in the alkyl group mentioned in the text?
1
Which compound is referred to as '2-methylpentane'?
55 CH3 44 CH2 33 CH2 22 CH 11 CH3 CH3
In the text, how many hydrogen atoms are present in the alkyl group of methylpentane?
4
Which compound has the longest carbon chain among the options given?
55 CH3 44 CH2 33 CH2 22 CH 11 C H3 CH3
Test your knowledge on the general rule 'like dissolves like' stating that nonpolar compounds dissolve in nonpolar solvents, and polar compounds dissolve in polar solvents while nonpolar and polar compounds do not form a solution together.
