Answer

1) The lewis structure is drawn the way the molecular formula is written. 2) The dipole moment in C-H bonds is towards carbon and in C-N bond is towards Nitrogen. The molecular dipole is towards nitrogen. 3) The compound has a large dipole moment.

Work Step by Step

1) Three $CH_3$ are drawn attached to N. The lone pairs are drawn on Nitrogen. 2) The dipole moment in C-H bonds is towards carbon because carbon is more electronegative and in C-N bond is towards Nitrogen because nitrogen is more electronegative. The lone pair on nitrogen contributes to dipole moment. The molecular dipole is towards nitrogen. 3) The compound has a large dipole moment.
