Question

match each two - dimensional structure to its correct three - dimensional description. drag the appropriate items to their respective bins. view available hint(s) linear trigonal planar bent tetrahedral trigonal pyramidal

Explanation:

The shape of a molecule is determined by the number of bonding pairs and lone - pairs of electrons around the central atom. Linear has two bonding pairs and no lone - pairs. Trigonal planar has three bonding pairs and no lone - pairs. Bent has two bonding pairs and one or two lone - pairs. Tetrahedral has four bonding pairs and no lone - pairs. Trigonal pyramidal has three bonding pairs and one lone - pair. Analyze each structure based on these rules.

Answer:

1. For \(Y - X - Y\) with no lone - pairs on \(X\): Linear
2. For \(Y=X = Y\): Linear
3. For \(Y - \ddot{X}-Y\) with two lone - pairs on \(X\): Bent
4. For \(Y - \ddot{X}-Y\) with one lone - pair on \(X\): Bent
5. For \(

$$\begin{matrix} &Y&\\ &| &\\ Y - &X - &Y \end{matrix}$$

\) with no lone - pairs on \(X\): Trigonal planar

1. For \(

$$\begin{matrix} &Y&\\ &| &\\ Y - &X = &Y \end{matrix}$$

\): Trigonal planar

1. For \(

$$\begin{matrix} &Y&\\ &| &\\ Y - &X - &Y\\ &| &\\ &Y& \end{matrix}$$

\): Tetrahedral

1. For \(Y - \ddot{X}=Y\): Bent
