How do you draw the electronic dot diagram for methylcyclohexane?

Here’s what I get.

Explanation:

Join six carbon atoms in a ring with a seventh carbon atom off to the side (Figure 1).

Fill all the unfilled valences of C with H atoms (Figure 2).

Each line represents a pair of bonding electrons.

There are no lone pairs, so Figure 2 is the electron dot structure.

the enthalpy of formation of water is given as -285.8kj/mol, which states that the enthalpy of formation is negative.

negative enthalpy of formation indicates that the heat is released during the reaction process. the heat is released from reaction to the surroundings the enthalpy is expressed with a negative sign with the energy given out in the reaction process.

the formation of water takes place by giving out heat which is -285.8 kj/mol.
