4. acetonitrile (h₃ccn) has many uses, including as a solvent, for spinning fibers, and in lithium - batteries. it is primarily found in air from automobile exhaust and manufacturing facilities. acute (short - term) inhalation exposure results in irritation of mucous membranes. chronic (long - term) exposure results in central nervous system effects, such as headaches, numbness, and tremors. (pubchem) do you agree with the following statement? \a triple bond forms from three sigma bonds. in the molecule h₃ccn, the sp² hybrid orbitals of both carbon atoms result in the trigonal planar electron group arrangement.\ if not, revise the statement so that it is correct. either way, justify (and illustrate to explain) the statement (new or old).

Answer

Explanation:

Step1: Recall bonding and hybridization concepts

In $H_3CCN$, the left - hand carbon (connected to three hydrogens) is $sp^3$ hybridized, not $sp^2$. The right - hand carbon (in the triple bond) is $sp$ hybridized. A triple bond consists of one sigma ($\sigma$) bond and two pi ($\pi$) bonds. The statement about the $sp^2$ hybrid orbitals of both carbons is incorrect. Also, a triple - bonded carbon has a linear electron - group arrangement, not trigonal planar.

Step2: Correct the statement

The correct statement could be: "In the molecule $H_3CCN$, the $sp^3$ hybrid orbitals of the left - hand carbon are used to form sigma bonds with three hydrogen atoms and one sigma bond with the other carbon atom. The right - hand carbon is $sp$ hybridized and forms a sigma bond with the left - hand carbon and a triple bond (one sigma and two pi bonds) with the nitrogen atom. The triple - bonded carbon has a linear electron - group arrangement, and the non - triple - bonded carbon has a tetrahedral electron - group arrangement."

Answer:

The original statement is incorrect. The corrected statement is as described in Step2.
